If I hold down the up button on my driver's side window it starts clicking right before the window is almost rolled up (about 1 inch away). In order for me to get the window to roll up fully, I now have to tap the up button when I get close at the top.

It's a 2000 SS, anyone know what this might be?

Motor and regulator were replaced in '05

What kind of clicking, like a relay? Or is it more of a clunking sound?

AceTen21

clunking, only at the top though.

Your replacement window motor was probably bolted to the regulator? Those bolts have probably become loose, allowing the motor gear to disengage the regulator when it starts feeling resistance as the window comes to a close.

Tighten with some thread locker and that should probably do it.

I just had a motor where the internal gears were completely stripped in the up position, but it would go down just fine. I'd have to help it up.

So it looks like I need a new regulator. What would cause this??

Would you guys recommend I spend the $54 at autozone for a new motor while I have the door apart, the GM replacement was installed in fall 2005.

Here's a video of the problem, the window clunking at the top:

Thanks in advance for any help guys.

Yea, time for a new reg. If those are the teeth that mesh when your window is almost all the way up, your last motor was probably not installed with the gear fully engaged. (Or it may not have been loose against the regulator.)

While you work on a repair, you might have some luck pulling up on the glass when you shut the window. This should keep the popping from happening but requires that you have the door open.

OK, thanks alot for you help.

Mine did the same thing, rounded off some of the regulator teeth and started clunking. I bought a regulator and motor off ebay, since both were cheaper than just the regulator from the parts store/dealer.

Installing it is a PITA.

Yea, that's a good point. Another thing is that if you rivet the new regulator in, you'll need special rivets from GM. (They are steel mandrel and aluminum jacket rivets, designed specially for the composite door material.)

Be careful. This is what happens when you use the wrong rivets: https://ls1tech.com/forums/general-m...-included.html

I will keep that in mind as i have done well over 100 window motors and regulators on f-body's with the same rivets in the past 12 years. I personally believe if your a good wrench and you know what your doing, there is nothing that cant be properly repaired.

g/l to the op.

I ordered the autozone dorman regulator/motor kit. Do I have to use rivets? The reason I ask is because I dont own a rivet gun.

Many people use bolts for the motor to the regulator. I'd recommend using rivets for the regulator to door connection, though. They will be much kinder to the composite door. (There are special rivets that you need to get through GM.) The rivet gun needed is heavy duty, but any auto glass shop should be equipped with one.
