Question about 2005 Chevrolet Silverado

1 Answer

Rear doors won't close when cold

2000 Silverado, ext. cab When it's cold the rear doors don't close tight (if at all), when the interior of the truck warms up they are fine. The first time I told the service manager about this I'm sure he thought I was making it up. This morning it was 6 degrees so I drove to the dealership without ever turning the heat on. I froze, but now the service manager knows it's a real problem. The service manager is looking for a TSB, but he said this was the first time he had seen this problem. Others have written about this problem, has anyone found a fix, or a TSB? I believe that others may have this problem and not know it because they don't use the rear doors all the time. I believe this is a safety issue because the front doors won't close tight if the rear doors don't. Al Smae problem with my 05. First cold day the won't close and then after being outside all ngiht they won't open. The hood won't open either to allow me to plug in the block heater. I worry about the cheap plastic handles breakign so I don't force them.

    Had it at the dealership this week, they cleaned and lubed all the latches while it was in for an oil change. Better, still takes three good slams when it's -30. They weren't surprised at all when I raised it.

    Now to get the power lock on the passenger side working when it's cold.......

I'm assuming different lubrication has been tried on the latches right? Has anyone tried adjusting the striker at the post where the door latches, outward toward door just a slight bit at a time, just to see if that helps? It almost sounds like something is expanding & contracting just enough to cause problems once it hits a certain temperature, like door panel or something, or maybe even the door seals/weatherstripping, will not compress enough to allow proper closure once they hit a certain temperature, or maybe even the door itself is taking a little different shape on at certain temperatures? When the door won't close/latch, take a screwdriver or similar, with door open,and push it against the spot where your striker would normally hit, kind of like using screwdriver to act the same as it would when door closing on striker. If it snaps around your screwdriver, then releases when you pull or push handle as you would to open the door, then that part should be o.k., but try it a couple of times to make sure. If o.k. that's where/when, I would try moving the striker on body toward door, (outward) a bit at a time, and see if it helps. If it works, then adjust that striker to point of working, but not too loose as to cause windnoise. Let me know will ya' I'm real curious now.

    If it hasn't been done, I'd get a can of spray silicone, and spray all around the seal for the doors, that are on the body of the truck too. When I need to spray mine off at carwash to get salt etc of it in the winter here, and temperature is below freezing, I give all seals a quick coat of silicone to eliminate frozen door, and spray in and around locks before, I do. Works for me.

Not sure, but I've heard a bad hazard switch can cause strange problems.
Also, if your truck has a body control module that controls interior and lights, that may be your problem, too. Good luck.

I don't believe the window issue is related to the door adjustment. But the interior lights flashing are> It would be the same instance if you were opening & closing your drivers door while driving. The rear door isn't closing tight enough to shut door jam switch.

Door ajar light now is on and interior lights won't go out all doors and rear window close tightly what else can I check or do?

those are a little more complicated then the old days. The switches are now part of the door latch inside the door. Does your truck tell you which door is ajar? If so you will need to replace the latch on the inside of the door or bypass it.

I lost my head lights, dome light, horn door

sounds like you have a bad ground somewhere. Check every ground strap that you can find, make sure it's tight, and not corroded, etc. Sounds like the accessories are trying to find a ground, and going through the brake light to do so, thus burning out from too much current.
