GMT400 crew cab pickup; I don't know the exact year. It used to be a police vehicle, so the rear doors don't work from the inside (nice bars on the windows, though), and the front passenger one doesn't either. I would like to improve this situation if possible. The main issue is that this truck is located almost at the North Pole (no, really) and I can't exactly drop over with a screwdriver and a wrench. My idea is to acquire the parts, ship them north (they get a plane twice a week, weather permitting, and a barge for bigger stuff once a year), and get them installed by remote control.
Anybody know the best place online to find an exploded diagram of GM truck door workings? Also, what do I call the necessary parts in GM-speak? (I tried looking on Rockauto briefly, but nothing jumped out at me.)
Thanks!
Not sure on the rear doors(did they check for the little child lock switch near the latch?), but for the front passenger, with GMs this sort of problem is typically the little plastic clips(you want to ask for "door rod clips") that hold the linkages together, they get brittle, shatter, and the rod falls out. Disassembly (remove door card) by a individual of above average mechanical inclination should immediately reveal the problem.
It should be noted that when working on GM interiors, you really want it to be as warm as possible, like 60+*f, or you'll be breaking even more brittle plastic getting the door card off.
Kenny,
I'm pretty sure that this was a case of "rear interior door handles inop" as part of the police-spec upfitting. In my experience, GM sometimes but not always sends the unused parts along with the vehicle in a little baggie, but that's pretty much a moot point after this many years. Thanks for the terminology, and excellent advice on the ambient temperatures!
I'm not sure how they go about disabling the handles. It might just be a linkage disconnected or an operating rod removed. If they can take the door panel off and send pics that'd make it way easier to see what needs to be done.
Edit: replied before I read Kennys post. What he said, and good call on the temp thing.
they almost always just drop the parts in the door. pop the panels and have a look see...

Care to elaborate on the circumstances here? Just curious. If it's personal or private no problem. The vehicle is near the North Pole, you are shipping the parts up but someone else will be putting them on. Are you ever going up or is the vehicle ever coming back down and how did a police vehicle end up up there in the first place? Doesn't seem like a high crime area.
the rear doors on my 94 9C1 Caprice just had the linkages to the interior latches unhooked... everything was there, just not functional.
Thanks to all for the replies.
It's not confidential, I just don't know a lot. A good friend is the principal of a school in a very small town way, way up there and this is the Community Truck, apparently. It's ex-RCMP, and I honestly don't know if they got it from the local detachment ("detachment" probably means "Constable Bob") at the end of its service life or just barged it in from somewhere else. At the moment, from what I hear, inside door function is an issue: the back ones because ex-police, and one or both of the front ones because ex-working. The local temperatures undoubtedly played a role in this situation. I'll ask about the possibility of finding disconnected but viable parts inside the back doors as soon as it's warm enough to go poking around.
