1998 Park Avenue Driver Side window problem

Do you have any pics or links showing the regulator? Is this assembly with the rails, and the cross bars , the regulator assembly?

Thanks again for the info..

What I found on our 1997 PA and on my parents 1997 & 2000 PA's drivers side window problem is that the rubber strip on the rear folds in and binds up when the window is going up.

Given that all 3 of our cars are doing this and we do know of another PA of a friend that is doing the same I am surprised to see that this hasn't been addressed. This problem would cause the failure of the arms/etc inside the door if a person didn't know what is causing the window to bind and would keep trying to move the window.

The glass itself is being held firmly enough and it tends to rotate a bit forward when going up and then the seal folds in.

It is my belief that the arms that hold the window in place, and guide the window up and down, begin to get worn, and loose, and allows the window to tilt forward, which is why the window seems to bite the rubber trim near the rear of the window. if you grab the top of the window, and pull upward, and downward, and forward and backward, you will notice it is looser than it appears. Check it out and let us know what you think.

I think the problem is not the rubber, but rather, the parts inside the door.

I have a 97 PA and have a similar problem with the driver side window. Except that mine goes part way down, gets really slow (sometimes, when it's cold out trips the "auto down" feature) for a while, then speeds up to full open. I'm going to check it this week end for regulator binding. Are the motors for all the doors the same? The way they are mounted, it looks like they might be. If I can use one of the motors from one of the rear windows it would save me some $$$. Don't really use the rear windows anyway.

Thanks

When you disassemble the door, you'll notice the 2 metal strips that criss cross, and they slide along a track. add some grease to the track to allow it to slide better, before yours gets as bad as mine. Upon searching, I can only find the motor and reulator together, and not seperately. This is the only reason you or I would need a new motor. It sounds like your motor is fine...it's the rugulator (metal strips the ride in the track), that is the problem.

I think yours is getting slow, but not loose and sloppy. If that's true, some grease in the track should do the trick. smear a thin layer across the inner part of the track where the end of the ragulator slides, but don't put so much that it cakes and gets on the window, or collects a ton of dust and debis. Had I done that in the beginning, I wouldn't have my window tilting almost far enough to fall out. I'll be forced to buy the motor and regulator as one. I have not bought one yet, as money is tight. My passengers window is doing the same thing, but not as bad.

Good Luck. I hope this was helpful.

Thanks for the info. I'll check it out this week end. Through some research, I found that the motor and gear assembly for the driver door and right passenger appear to be the same. If there is a problem with the gear assembly, I guess I could swap them. I'll check the regulator and window guides first, though.
