Vannin' Community and Forums Forums Chevy General Discussion windshield 94 chevy

1st main job in my restoration is fixing the windshield, so it has to come out and rust cut and replaced.

im trying to get replacement weather strip in case the original cant be reused. Parts catalog for my van states i need similar to below i.e. left and right section with a capping joint in between




but my current seal dosent look like this, more like onec strip that's been heat bonded.



anyone any ideas what i should be after?

I believe the top diagram is for a 1995 and newer up till the body change.

The lower picture looks like our original one which was from 1978. When we repainted our van a few years back, we went with the newer 1995 version which works on the older vans.

It may be that is all they are offering now.

I had both of my 92 & 93 done they each have a different type of seal...the glass shop tried to do the 1st one found out it wasnt it ordered the other style it went in fine....picked up a rock in the desert.....called the glass shop this time he came out with the other from the 1st install and he ordered another 2nd style.....20 min later I heard a OH CRAP....the 93 used the one he got for the other van and the one he ordered he didnt have to.....soooo I know he has a seal for the 92 in stock.....but they both have a split at the bottom center.....the one in the pic is a factory seal done in house.....

Try http://www.am-autoparts.com

although the top image isnt from my parts book its exactly the same as my parts book, which is a 93-94 book.

so is the general consensus that what i currently have is how it was fitted when built but the top image will now replace this ?

no much joy on that site..

The drawing you have from the parts book showing the 2 piece thing, I believe is the optional chrome trim.

arrrrr im lost.


IS my windsheild a bonded or moulded?

Ill call my glass guy and get the part number, your & my vans are the same...I believe your is the same as my 92....the 93 had glass mods done to it at Armor Tec...

This is what the 94 service manule states

I called Marks , they order from there vender but she gave me the part # for the seals..

WKTB 1161 for the 93 & WKT 925 for the 92

If you can post a picture of the windshield frame on your van I can tell you what you have.

According to the page from the manual you posted you have a glued in windshield. You may be able to get it out without messing up the 'trim', but it's best to just order the new glass with new trim.

the guy in the parts place was implying that. Why would i have to get new glass??

Sorry, I thought you were looking for glass. I just reread the top post. You can cut these out and glue them back in. That being said, you may want to pay someone to remove and reinstall it when you are done. The break really easily if they are not cut out perfectly.

Ken will give you all the glass from his van...he hates glass...lol

yep i took it to the guy im going to get to do the work and thats what he was saying cut the outside molding off cut the glass out fix what ever needs fixed then bod the glass back in so it is sealed and then glue the molding back on top so its mostly just decorative ans the window has been bonded already.

On my '94 I'm replacing my cracked windshield and repairing some rusty spots. Mine is a one piece gasket that goes all around the glass. It has been replaced before and the last installer had gobbed sealer in behind it but I'm not sure it actually needs any sealer. I'll find out when I talk to my glass guy.
A picture of the windshield cradle after prep:

Well....I'm finding out this morning that the one piece gasket is a modification and not OEM to my van. My glass guy will replace per OEM (glued in w/ inner and outer trim) but he won't reuse the one piece gasket as it is a liability because it's a change to the original design.
I didn't know windshields could be so complicated.

lol tell me about it.

Interesting your doing this just now catfish. so when you say "Mine is a one piece gasket that goes all around the glass" how dose this get kept in place on the frame once it is put back in, is there a locking strip or something that is wedged in on top off it?

Howdy Phils
Yeah there's a attached locking strip around the middle of the outside portion of the gasket. It hinges down into a slot, expands the gasket and locks the gasket in place. The outer edge of the gasket fits over the metal lip of the windshield frame and the inside of the gasket has a slot that the glass fits into.
I thought it was factory although I have seen windshields on similar models that looked different. My windshield gasket is pretty wide on the outside compared to some others.
I've got a call in for a different glass guy to see if he can tell me more.

Just got off the phone with the second glass shop and they said basically the same thing. He said that new gaskets were no longer readily available and to reuse the old gasket he would not guarantee the work.
If he seals the new glass in then it's a lifetime warranty.
His comment was that a "shade tree" shop must have reused that gasket along with all that caulking last time.

I'm gonna get the Ford windshield replaced at the same time. They're like kids.....can't get one something unless I get the other one something too.

The old factory rubber gaskets went out of style a few years back (more like quite a few). The factory went to urethane sealer and a molding at some point, but I don't know exactly when. My 91 has it, a friend had a 93 with the old style rubber gasket (could have been changed). Many years back, when I did my 77 G-20 6 wheeler, my glass guy put in my windshield with sealer and a molding. It looked different, but I liked it. Bottom line, go with the urethane. It seals better and should slow down the rust problems caused by leaky weatherstripping.

Phils you will not have a problem getting a new gasket for your van....our G series, Mark's glass had no trouble getting new seals for my 92 or 93..both done with in the last yr or so....

GUYS HELP ME :-(

i don't seem to be able to verify anything 100% with what yous say. When Catfish described

"there's a attached locking strip around the middle of the outside portion of the gasket. It hinges down into a slot, expands the gasket and locks the gasket in place"

i thought this must be what i have, so i went out tonight and checked. I was thinking the locking strip was the red hatched part in the middle of the gasket as below and hinging along the yellow line, but on inspection mines really dosent look to be like as described. the gasket you see below all seems to be one complete unit that is joined in the middle of the screen at the bottom (as per my first picture)



am i over complicating this and is it just a case that i need some or all of the circled items below



if not have any yous guys got a parts diagram of what i should get? i can seem me ordering the total wrong thing and getting it shipped at a ridicules cost which when ill start crying :-(

Here is who did mine & the guy that got my seals....go online and pose him your questions ....tell him I sent you, his words "Oh yea the guy with the big red van"....

http://www.marksglassservice.com/

Well the glass guy showed up this afternoon but didn't replace any glass.
It's a long story.......

Ok..
Since we know Mark knows what he's talking about I called Mark with Marks Glass but he was out (it's already late here now anyway). Talked to a super nice young lady who said Mark would be glad to offer help. Even though I'm on the opposite side of the country.
Frscke, thanks for the link.
I'll try to catch him again tomorrow.

Welcome

ivee-mailed him too, will keep you posted.

So this is looking like the one i have installed (wont be able to confirm until i remove it)

Catfish dose this look like what you had when you removed your screen?

Below is from the UK suppliers GM parts system.

That looks very much like mine. Mine is however one piece, completely around the windshield, with the locking strip attached. The view "A" is exactly like mine.
I should've took some pictures this weekend. Too many projects.

yep, the join on mine is sort of 'rubber welded' see my first picture, is that what your is like? please say yes :-) it means im finally getting somewhere.

I think they're the same.
I am seriously considering reusing mine and installing the window myself.

the supplier over hear that ive been in dialogue with regarding the seal says for this type of seal it CAN and USUALLY is reused when putting the window back in.

OK.. the second (or is he the third?) windshield guy came by today. He had the windshield that fits the '94 with him but it won't fit the old style gasket because the '94 was a factory glue-in. He said that the windshield being changed from a newer glue-in type back to the older gasket type was a popular thing for glass guys to do and was good because, in his opinion, the gasket is better. However you have to have the proper windshield to go with the gasket. He sounded like he knew what the deal was and has been doing auto glass for 30 odd years.
He has ordered a windshield to fit a late '70s model so it will match with and we can reuse the gasket. He's scheduled back Wednesday afternoon with the late '70s glass so I'll have more to post then.

Whew....! It's just a windshield ain't it Phils?

WOW what an ordeal....

tell me about it. I picked this Seal up on ebay over hear for 0.01 pence. worth it just incase it can be used. some pictures of the windsheilds and seals would help me a lot catfish

while catfish comes back with how he got on below is a post from Chevy Talk forum on how to install a windshield into a Precision WBL 853 seal (i just picked one of these seals up on ebay for 1p)



ist a lottery i know but will this work with my 94???

"Completed the windshield install in my 1989 Chevy Van G20

Note I used the Precision WBL 853 rubber molding, which is a removable locking molding (no separate locking bead, the molding locks into itself).

This is how I did it.

Unless you have done this before, it can be confusing as to which groove of the molding goes on the pinch weld, glass, and which part is twisted for locking. The groove that locks the molding goes on the outside. The fine narrow groove will go on the pinch weld and the wide groove whose width is about the thickness of the glass will fit the glass.

1. Prior to installing any part, place masking tape on the outside frame of the windshield. Just the outer most part of the frame where the outer edge of the molding will rest when installed. This is to make it easier to clean up any butyl caulk that will squeeze out after the install.
2. Slip the molding on the pinch weld. (This is not the type of molding like most others where you install it first on the glass and use a rope to pull the molding over the pinch weld to mount the windshield.)
3. At this point the molding outside edge can be easily lifted to allow a bead of Butyl caulking. Fill the cavity under the rubber with Butyl caulking, which will spread out and fully seal the molding to the body, keeping water out from under the windshield molding. Caulk it all the way around. When you install the glass and lock the bead, there should be enough caulking that a small amount will squeeze out over the masking tape. Butyl is very sticky, stringy and very messy. Clean up Butyl caulking with Mineral spirit.
4. Place the windshield in the bottom molding groove and center it while pushing it down. The top of the glass will not go into the groove easily. By slapping the glass with your palm (hand full open) and in a downward directions, the glass will go down as much as possible. Do not apply any point pressure on the glass as it will probably break.
5. Now start at one of the top corners and with a bone tool force the rubber lip from the inside, out and over the glass. I used a couple of my plastic trim tools to do this along with some soapy water in a spray bottle, which will reduce the chance of damage to the rubber. Do this on both upper corners. This will be the hardest part of the job. Take your time and be patient and it will go in. If you become frustrated take a break, calm down and come back later. Don’t risk breaking the glass. Finish seating the glass at the top between the top corners.
6. Now while on the outside of the vehicle, carefully pry up the inner edge of the locking bead (the glass causes it to fold in and under the outer edge) while pushing down on the outer locking beam. The out edge of the lock will slip under the inner edge of the lock and lock in place. To make it lock easier, use soapy water in a spray bottle. Once you started to lock the molding it does not want to stay in place, so you will have to apply pressure while continuing to push the rest of the outer locking edge into the inner locking edge. To lock the bead will take some time, but go slowly and you will get there. As you are locking the bead, you will have more butyl squeeze out. Clean it up as you go, because sooner or later some part of your body will stick to it and make a mess. Mineral spirit works well to clean off the Butyl.
7. After locking the molding in place, peal back the masking tape carefully as the part of the tape under the outer edge of the molding may rip off and make it more difficult to remove.
8. That’s it. Clean up and you are done.

'89 G20 5.7L"

It's in!!!
The old gasket worked fine. Some pics:
The glass slide into the gasket only requiring a little help snapping into place. Here's the locking strip before it was locked in.





And the locking strip after it was snapped into place all the way around.



The installer used just a little sealer behind the gasket along the top edge only and then used a very thin line of sealer between the glass and the gasket all around.
The windshield is for a late 70s van. He wrote up the job as a 1978 Chevy van.

Phils, did you note that my new windshield glass part number and your windshield seal part number match?

ohhh congrats Catfish, hope mines goes as well.

yes i did, interesting. going home to check my seal now?

I literally went through this exact same entire ordeal. No joke- a 3 week process...

I had 6 visits from Safelite. I even queried about the locking gasket and if I needed to get a new one, or if they bring that, etc.

Long story short

First guy came out and installed the window with just glue, and put a tiny trim ring around that left a 3/4"x 1" gap in the pinch weld to collect water and debris.

first guy came back to replace window, with locking gasket, took him literally two days- all day doing it to get it in.

Third guy came out with new windshield, generic NOT Pilkington like the first (waves in glass, etc) because the first guy scratched the window a bunch tooling it into the seal. Brought the wrong window with mirror mount.

Fourth guy came out the following week with "correct" window, which was also a cheap generic- even pointed out the flaws and wavy glares in it. Recommended I go to their main shop to see if they can buff the OEM Pilkington window that was scratched.

Shop manager came out and agreed while taking note of the window trim scratched from previous installer (who is now fired), ended up going out to their shop to have window buffed- got free can of glass cleaner.

Unbelievable.

The guy who removed the window was actually very familiar with that locking style saying they switched later to those instead of glue in because they sealed tighter and better than the glued ones. The one piece locking strip was sealed a bit to in corners and what not in the end, but after I fixed the pinch weld and corrosion, it looks a lot better.

I tested mine with a water hose and it seemed water tight. Of course you can never tell til it's actually rained on.
I was lucky that I finally found a guy who had some experience with the gasket before any damage was done.
Oh yeah, I got a free can of cleaner too! Best glass cleaner I ever used.

So what you're saying is they went back to the old style rubber gasket with just a newer style? Interesting....

Holy thread revival batman.....

This is a windscreen gasket I got with a new windscreen that I received from Germany many years ago. The windscreen company ended up re-using the original gasket. Can anyone identify what years it is for?
It is for sale but DBnate on here has first dibs on this if it suits his van.









And a little drawing I did of what the side profile should look like......

The following is to the best of my knowledge:
The sheetmetal around the windshield was unchanged from '73 to '95.
The windshields were changed to fit either the glue-in seal or the lock-in gasket.
In other words, if you have a gasket type windshield your gasket will work with that glass regardless of the year.

Our 1994 GMC was a glue-in from the factory but was changed to the older gasket type later. The only difference was the glass and gasket itself. I was told that this was a fairly common practice if the glass shop repairing the glass happened to already have the glass and gasket in stock.

The gaskets are getting harder to find nowadays as they were stock on the older models.

Thanks Shaggy unfortunatly wrong type for my van appriciated though

Nate

I guess I'll hang onto it just in case mine ever needs it.

I'm going through this nightmare now on my 1980 G10. Glass guys replaced the windshield after I fixed a bunch of rust. Came to pick up the van and they ended up reusing the old rock hard gasket because he said he couldn't get the new gasket to fit. Two days later, we have a downpour and of course its leaking just as bad as it was originally.

I tried to explain to the guy to order a newer glue in style glass and trim, but he just looked at me like I didn't know what i'm talking about. It's so rainy in the northwest, I figured the glue in style would be better.

Just found this thread after my local installer (Seattle area) did a bad job replacing my windshield seal on my 1991 G10 - basically inside the van after the install I can see the back of the pinch weld and there is that black glue visible all around the pinch weld - and then on the outside - the rubber (gasket?) is very poorly attached (glued?) all around it - its not even straight. Just a terrible job. Its going back to them on Wednesday and hopefully they will do a better job this time. Also the rubber that goes around the outside doesnt go out as far on the body as the old rubber - and that means the new rubber exposes an area where the body shop didn't work too hard to get flat since they thought it would be covered up !

You need this kit and a competent glass installer who has experience with Chevy/GMC vans! I too found out the hard way.

Thanks NateB - my saga continues - the local Seattle (Issaquah shop) replaced the seal they shoddily put in first - and at first the replaced seal looked like a good job - two weeks later the outside rubber gasket has started to come away from the body and it appears they have just sort of glued it on with a thin line of that black sealer so there was NO WAY it was going to last - and on top of that I can see they have chipped paint away in a couple of places under the seal - presumably while trying to get the new seal in and out and in or whatever .. . . this is getting so old .. . .

Nate I am going to buy the seal you mentioned - and they try and find someone competent to install it. If it works out I will response on this thread since its the one people will get Googling.

Here I am again 6 months later - thought I found a great installer - well its already leaking in 3 different places and literally killed my car stereo..... at this point I will literally drive anywhere in the western states to find an installer who has the experience and knows what they are doing - I just can't accept a leaking windshield .... anyone have recommendations?

I don't know what the cure is for these, perhaps to use the old style gasket and load it up with sealer on the install. My 91 leaked from over the glass on the right side somewhere too and I don't know that one had ever been changed.

Thanks Pontiac59 - me neither. I am now considering doing it myself - which seems like a fools errand when people who its their ENTIRE JOB can't seem to get it done right. If I can't find someone to do it then I think I will go with the old style gasket that is mentioned here - but what I don't know from here is:
1 - If I can use the same windshield I have or if I have to get a 1979 one
2 - If the windshield rubber comes with the locking strip (and if not if its possible to buy one)

I would love to be able find a competent installer who can save me the trouble. I am convinced that no one in the industry gives the tiniest s**t about what they are doing.

I would ask about rot but I see you're in Washington, from what I can see rust isn't a huge issue there.

The 94 I have now was garaged most of it's life but still has three holes above the drip rail, some rust below, and leaks a little at the base of the windshield where there's more rust below the edge of it. I need to get off my butt and take the vent screen off and clean that out and run some filler in there. Not ideal but okay for now. I temp fixed a couple of the roof holes with duct tape. lol

Thanks - yeah it definitely did have rot - but the first glass shop I went to had a body shop next to it and they patched it before the glass shop did their attempt one (the attempt where they didn't even use the internal trim), their attempt two was the external rubber peeling off in a week - then I found an old school guy who was up front about what a hard job the glue ins are and that there was a good chance it would leak after - yes in 3 places. I got hold of the old school guy yesterday and he is going to put in the 70s rubber for me and thinks that will do it.

Nice job on the duct tape :-) My Maaco paint job is showing its age now with a couple of body rust spots I'll need to do soon. I really want to airbrush me as Conan on the side at some point :-) :-)

Hey all - just wanted to follow up here - my old school glass guy put in the old style seal in my G10 and now it is perfectly sealed. I highly recommend that anyone needing a replacement seal go to someone who can specifically tell you they have experience with these vans and that they understand the difference between the seal types - and then get them to install the old style seal. It is so darn nice to have my windshield all nicely sealed again and I can't believe how many tries it took across 2 different installers (fixed on 4th try). Anyways - good luck everyone and thanks for the help here.
