I already did the front doors, Problem is, on the back door there's nothing that the cylinder would tie into. There's nothing on the inside of the door that would allow you to lock or unlock the door, so I'm at a loss as to how the cylinder would function. | | | Re: No locks on 1977 chevy g30 rear door? | Joined: Nov 2017 Posts: 9 stranger | OP stranger Joined: Nov 2017 Posts: 9 | | | | Re: No locks on 1977 chevy g30 rear door? | Joined: Jun 2010 Posts: 18,286 Likes: 557 | Joined: Jun 2010 Posts: 18,286 Likes: 557 | You are missing the upper & lower actuator rods that are connected to that . When you push in the thumb part of the door handle it turns just like yours but the rods that actuate the upper & lower locking mech are gone.

I knew it had to be missing something since there was no physical lock on the inside of the door. I'll have to make something work.
Thanks again | | | Re: No locks on 1977 chevy g30 rear door? | Joined: Jun 2010 Posts: 18,286 Likes: 557 | Joined: Jun 2010 Posts: 18,286 Likes: 557 | Go to a junk yard n pull those rods out of a door. You will see how to take out & know how to reinstall... Practice on there vans not yours ! Remove the whole assy, 4 screws on the bottom of the door & 2 bolts on the top of the door, 3 bolts to remove that lock assy you have & the whole assy comes out.

OOOOOhhhhh I just realized you have a 77 .... all I saw was G30 .... so your driver rear door clips to the van & the pass rear door locks onto the driver rear door ? You may not have the upper & lower locking clips on the pass rear door as mine does.
Things changed in '88, SRY for the mis info.
That pic was from a '93 factory service manual.

Pushing the button on the handle opens the latch and allows the door to open, so my work around was to stop the action that allows the latch to open. | | | Re: No locks on 1977 chevy g30 rear door? | Joined: Jun 2020 Posts: 257 Likes: 48 enthusiast | enthusiast Joined: Jun 2020 Posts: 257 Likes: 48 | Thread revival!? I replaced the cylinders on my sliding door and my rear door on my 87'.
Both seem to have all the rods, but the locks don't lock properly. The sliding door has the inside latch, when I turn it it starts to move the mechs, but never actually locks. Same with turning the key on the back.
They were originally power locks.
