I replaced my weatherstripping about a year ago, and ever since then I have to really slam my doors when my windows are up, if I crack the windows a bit they close easier. Its almost like there's too much pressure getting caught inside the car when I try to close them. I tried adjusting the striker but it didn't help any.

I'm thinking I read somewhere before that the electric hatch motor is supposed to raise some when the doors are open to relieve pressure, is that true? My hatch motor was "fixed" by the previous owner, I have another one but haven't put it in yet.

I can say that I have an 86 with electric hatch and it has never automatically lifted when the doors were open. And as far as I know the motor is working as intended, it still pulls down fine and goes up when I open the trunk just fine.

My doors have to be slammed some to, but I always thought it was just cause the new weatherstripping wasn't conformed as well to the glass. It has been about a year since I replaced mine and it's still like that but I've never given it much more thought. I've still got to get my weatherstripping worked on again because the crappy t-top seals from 1a auto doesn't fit correctly so it still has a couple small leaks if rain hits it in just the right way. Just got to wait till I have the money and time to do it, going to pay someone else to do it this time instead of me doing it so that if it still leaks I can make them fix it.

I have original weather stripping on my car, and I still have to slam the doors when the windows are up. When they're down though, they shut super easy. It's something you gotta get used to.

Well my driver door is worse than the pass door, so I think something is wrong with the latch. I've had other thirdgens and never had to slam the doors this hard. The pins have been replaced and the doors do not sag

the window regulator may be worn out and causing the widow to be on a bad angle or up to high when closing so it basically slaps the new weather seal rather than tuck up behind it. That would cause the door to bounce back and need to be slammed to close. Does your window have a lot of wiggle when up?

Steven6282

Mine does, are you saying there is a way to fix that?! I'll be all over that project next week if so lol.

Red 87 GTA

if it has alot of wiggle you can pop the door panel off and basically adjust so the top of the glass leans over toward the car more making it tuck up behind the seal. there are adjustments for the angle of the glass one on the rear regulator track and one for the front its basically the tri seal thing. You can also play with the windows max height a bit to make the new adjustments work. In the end its basically trial and error till it works with small adjustments and things don't be afraid to play with all the adjustments and see what they do

Also to those that have the window just slap the seal and not close right these adjustments may fix that too

Steven6282

Ahh, yeah I've played with the height adjustments and gotten the closest seal I can get already. Thought there might be some other trick I could do because it still doesn't seal great. But as I said before I'm pretty sure it's a problem with the weatherstripping. The main place my seal has problems is where the ttop sits into the body seal. The two separate pieces don't come together tight enough or lined up well enough for the window to create a good seal there. Resulting in rain being able to seep in through the cracks.

The problem imo is the stupid little arms poking off the body seal at those places. They aren't reinforced by anything just poking out like little stubs, very easy to bend. So the pressure of the window will push the entire seal back there instead of tucking under it.

My window does fit into the weatherstripping groove like it's supposed to, but it is pretty tight.

The electric pull down is there because of the air pressure problem with these cars. It was put there because when you tried to close the manual hatch with the doors closed it would not close sometimes. The electric pulls it down gently to avoid the problem. It's normal for the doors to grab a lot of air when you are closing them, they are big doors. The solution is to swing them almost closed slowly and then just slam the last 2 inches or so.

Having the door shut problem also... passenger window is firm when open the glass wont shake but driver side does have almost inch of horisontal movement as if the glass would be loose, any idea if some tightening would do the job? (its 0Farenheit outside so better ask first and then freeze rather than freeze to death)

Yeah my driver side glass is loose too, I can actually shift the window forward and backward, this is probably my problem.

Kerodal

i got 89RS and it started to get loose as winter came... also trunk locker does not work
ill try to see what the problem is when it gets bit warmer in here

Ok got the car to a hall and checked the window holders and such, had nothing wrong, and after re-assembling the whole thing so that the door PANEL was well attached the door stopped rattling and closed just fine.
