Hi,
I have a 1994 Chevy G20 and the driver's door lock switch has stopped working. I've been shopping around for a replacement but can't find an aftermarket one available anywhere. There are plenty available for model years up to 1993 and then from 1995 and newer, but for some reason no 1994. I checked and the 93 version is different from mine. Any suggestions on where to find or other compatible model year lock switches?

I've been a long time Vanning browser but this is my first post so hopefully I am putting this in the right forum.
Thanks

Welcome to the site ....

You can search Chevy G10 G20 G30 GMC 15 25 35 ...88-94 for parts for your van.

'94 is when the Express parts started the body changed in '96... honestly id go to a yard and get a few for the same price.

Hey 94,

Lubbock WrenchaPart in the am, I'll put it on my list, google them, type Chevy in the inventory search and scroll on down to see the Vans.

Midwest is producing a lot of old Vans at the Yards. Betcha there's a few near you. Welcome!

Hey 94,

Closed the Yard yesterday, ran out of time for interior parts.

In going back over your post, thinking about the "Loaded" doors they wanted to charge me an Arm and A Leg for, were rear doors, but the one had a Power door lock solenoid in it.

Door you know the switch is bad? I'd check for power at the switch. Fuse if no power. If power, check the switch for continuity, open, closed. Also the wiring to the door, all connections.

Do not know for sure but would think any of the Chevy trucks from 94 use the same switches……get new one from Rock Auto or places like LMC Truck NPD (National Parts Depot).


Recently purchased (10-2021) a 1991 Chevy G-20 “Shorty”. Past vans are a 1976 Chevy G-10 (purchased new in 1976 & sold in 1995). A 1978 Chevy G-20 Shorty purchased in 2010 and sold in 2015.

Hey 94, 22 today, bad weather until Friday, Hopefully the weekend will warm up and be sunny, and WrenchaPart runs another sale! Until then, hopefully you can source a switch. ParksGeek had my blower motor. You may be able to use your factory connectors on a truck switch? Maybe. Good Hunting!

LMK if you would like me to fetch you a switch.
Dr. Caldre's dash panel was under $20 to Georgia, A switch will fit in a free Priority Mail mailer.

Gday!

I don't know why 94 would be different. Inside they're the same through 95 and the 96 1-ton. But GM did like to change things here and there for no good reason.

If you had to you could change the whole door wiring harness to get the plug for the older switch. Or cut and splice.

The solenoid on these is up under the dash on the left - the whole power window and lock deal uses an add on harness chunk that runs across the body, plugs into the doors, and plugs in the fuse block. I successfully added that stuff to a '95 using '93 parts and it worked well but the lock solenoid lost the ground at some point.
