Power window hitting door?

**CD99Firebird** · 07-03-2015, 11:37 AM

When I operate my driver side power window, it feels as if the motor is banging against the outer part of the door.. anyone else have this issue? Any suggestions or ideas??

Sounds like something may have come loose in there. Probably need to pop the door panel off to see what is going on.

Does the window wobble?

No, it doesn't seem to at all.

Well that's a good sign. The motors do flex the fiberglass some. It could also be a crappy repair of the motor. A common fix is using bolts instead of rivets. Check to see if they came loose.

Definitely will.. thanks for the input

I had a customer come into my work for the same reason. The center pivot point of the driver front regulator had seemed to collapse on itself causing a loud scraping noise. I lubed the pivot point but advised the customer if the noise came back, the regulator would need to be replaced. Was a Toyota Sienna.

I'm not sure this is the same issue.. mine isn't so much a "noise", I just feel it hitting.. and it's not the outside of the door like I originally thought.. it's the inside.. I haven't had a chance to take the door apart yet...hopefully soon.

Sounds like possibly a bolt backed out of the track that connects to the glass. Keep us posted. Check everything inside the door.

Yeah, I will do that

As evidenced by this thread, the power windows on these cars have some flaws.
http://www.ls1.com/forums/f6/manual-...ormula-162508/
Eventually I was able to get mine working again because of a loose fitting connector on the motor, I bit the bullet and hard wired the motor.
I couldn't find it, but I believe I commented on another thread, more relevant to the specifics of this one, that I noticed that when the windoze
get to the down position, that it pushes the inside of the door in, something I saw from day 1. This leads me to believe that like the fine headlight
door system, the motor stop circuits are overcurrent deactivated. On the upshot, it's a hard stop mechanically, but on the downstroke, you're at
the mercy of plastic. Wrong material for a door. I got to the point where I would never put the windows all the way down, always left an inch or
so sticking up. Hope this heps.

The information is helpful, however.. I don't think mine is an issue of the window hitting the door.. the "thump" of something hitting the door happens immediately when I pus the power window button in either direction.. it doesn't happen again at the end of travel (in either direction)..

Sounds like the regulator is moving around when the motor first kicks on.

hmm.. seems like that could be bad news.. any "how-to's" on changing the regulator?

**pajeff02** · 07-08-2015, 08:00 AM

Our driver door will flex slightly when the window bottoms out. I always stop it just shy of the full down position. Completely agree that the design and execution of our power windows leaves a lot to be desired. It is what it is though...

I wouldnt worry about changing it until you make sure its secure. You could have a rivet or bolt that came loose that is allowing play in the system when the motor kicks on to move the window up or down. The window up and down motion depends on the regulator mounting points being completely stationary with zero play or movement otherwise you get noises and a sloppy window movement. I've had to deal with it myself and it turned out to be that the mounting bolts were loose which allowed it to move...hopefully thats all your problem is because it was a pretty easy fix.

I haven't opened the door panel yet.. but.. before I do, is there somewhere that is posted to show where the regulator is inside the door panel? I don't want to be lost once I open it up lol... thanks.

PM sent.

It's bolted/riveted to the fiberglass door frame. If you don't mind, once you take the door panel off please take some pictures of the door frame so we can get an idea of what's going on.
