Window motor clunk

Window motor clunk
Ever since I put in a new window motor on the driver side it makes a *clunk* as it goes down. it only makes the noise when the window is all the way up or when it is all the way down and i put it up. what gives? install was smooth and straight forward. still seals and works fine, just makes the clunk

Sorry to revive this thread guys, but I have the same noise on my drivers door so I'm going to take the panel off tomorrow and have a look. Was just wondering whether it's safe to dump that polythene sheet that's held in place by the black sticky stuff, or is it important to replace it after doing what I need to do?

If you are doing major surgery, you may find it easier to just get rid of the old barrier and get a new one from the dealer. If I recall correctly, they are only $10-15. The come delivered like a fruit roll-up with the sealant pre-applied. You just peel and stick. To clean up the old sealant and prep the door for a new vapor barrier - use a rubber glove, grab a dab of the old goo, and then use it to gather up all the old adhesive off the door.

ok - im with offspring and were looking at it. motor is secure and so is the regulator. we can't see where the problem is. The window also goes up/down at a slight angle but seals fine. Any thoughts?

I had these improperly adjusted at one point and got a clunk from them. (I think I had to back them off a bit and was stressing the glass too much.)

I think it could be that the gear teeth on the discount auto motor are a wrong size because i can sort of see them start to move, then clunk and the window goes down. I have heard of this happening with non GM replacements. no worries for now. everything is down tight and nothing is moving strangely.

Well, I've got this clunk too. Its on my pass side, and only when the window is all the way down. When I go to close it from this position, it'll clunk then work normally.
I did also replace the motor with a new one, but I used an OEM GM replacement motor. So I dont think its the aftermarket thing.
I tried seeing what was causing the clunk, but I have no idea. I didnt really look too close to all the rivets tho. I guess its something for me to do in the near future!

If all the bolts/rivets are tight and none of the regulator/motor parts are moving with the clunk, you might try looking at things from the top of the door. (with the door panel off) I've had issues in the past when I've adjusted the two felt pads bolted on the top of the door. Sometimes if they are pressing on the glass too aggressively, it will "pop" the glass as it starts motion and releases from the top and/or bottom stops.

Probably not. If you didn't touch the pads and didn't remove the regulator, the geometry of the glass/door should be the same as it ever was.
If the bolts/rivets are tight, there must be a hang up some where in the mechanism. One other thing to check is to make sure the bolts/rivets securing the motor to the regulator are not to long and causing the regulator to bind when it rotates.
