Cab Ventalation
« on: April 27, 2011, 01:45:51 am »
1983 Silverado K10   OK here is my question..  Has anyone had a problem getting the doors to close without really slamming them shut?   It seems to me that there is some pressure issues when closing the doors, I can watch the rear outside of the cab wall bulge when getting them to close tight.  I have replaced the door hinges, striker bolts and latches inside the door shell thinking that it was just all wore out.   

Are there any kind of baffles built into these doors to release any kind of pressure inside the cab when closing the doors?   I would think there would be plenty of places for the pressure to go,  I know on some other GM made cars that there are some sort of venting on the inner side of the door jam.

Are your doors aligned properly? How old are the striker bolts?

If you open your window a little do they close better?
Do you have the plastic bushing on your door strikers?

Brand new GM striker bolts, Hinges and latches less than a month old.   The doors seem to be aligned perfect according to the body lines..  Yes the doors close perfect with the windows rolled down a couple inches.

These trucks are known for that issue. They did it from the factory.

Yeah when me and my daughter are out, when we get out of the truck it's a race to see who can get out and shut their door first.  She hates it when mine gets shut first because then her's is harder to shut.   ;D

With the windows down though, my doors both dang near click shut.

There are vents on the door. Look for the louvers and make sure the flapper behind them isn't stuck. Like the others say, it does happen, but it sounds like you have an extreme case. Just thinking out loud here, but if you have air vents that you can open, would that help? (as in a truck without a/c)

At the bottom of the door on the inside, where the carpet would be under the door panel, there is a little grill(on mine, not sure about others) and behind the grill on the door are vertical louvers. At the very bottom of the door, parallel to the ground, there is a slot like 3 inches long and like an eighth inch wide. I can only assume that would be the "ventalation" for the cab pressure. I know the slit in the bottom of the door is a drain hole for water, but it could double as an air outlet. Check to see if those liuvers and slot are blocked? Only thing I can recommend.

I always open mine up before getting out-works great.
