Window Motors Questions.
Window Motors Questions. Ok, so I know I need new motors. My windows are so slow to go down they will also get started down then drop violently then they will catch and keep going down?
Sometimes they seem to die out halfyway up.
I also notice that it looks like they dont roll up all the way.
Question, would bad motors be the only cause for this? I have never messed with the motors in these cars before and thats why I have put it off so long but I really need to replace them both soon.
I know theres wirteups out there. What do I need? Just new motors or is there anything I should specificly buy?
Recommendations?

i just replaced my dwm, it wasnt hard at all. there is a nice write up on it, but it does sound like you may need a regulator as well. i bought a gm motor for $35, i know you can buy aftermarkrt with a lifetime warranty. i just dont like them, but that is my opinion. your going to have to take your door panel off to see why the window just drops, it might be catching on something.
All are motor issues except for the "catching up issue." You could have:
- bad rollers on the regulator
- grease issues on the track
- (most likely) a physical obstruction for the regulator, like a long bolt attaching the motor to the regulator, etc.
You'll have to get in there with a mirror and see what's going on. All of the above issues are fixable. The regulator is bomb proof and would rarely need to be replaced.
If you get new motors, I'd suggest getting lifetime Doorman motors. They are a new design that is supposed to last longer, will have a lifetime warranty, and are not rebuilt motors like the other brands and what the dealer will give you. (Doorman also sells replacement regulator rollers if that turns out to be one of the issues.)

Autozone had some for like 60 bux a peice IIRC.
They also had hardware and such but I dont think I need that do I? What if the rollers are bad?
My driver window didnt use to DROP as it was rolling down and im not so sure that they aren't rolling up all the way it just appears that they are not. There looks like theres a gap between the window and seal. The little piece of material at the front of the window the triangle piece where the outside mirror attaches.. Theres a gap there in that section.
Ill give it a look over once I get the motors.

i worked for gm dealerships, in the parts dept 25 years. yes they due sell rebuilt parts like starter''s alternators and you can also buy those brand new from gm. but window motors are new parts, the aftermarket rebuilds them and i know that because I used to sell them to the junk man that came by everyweek. we made a little extra cash that way.

If you have that front gap, you should check the back vertical track. Is the roller still attached to the bracket that is secured to the glass? That attachment point is known to break, which can cause uneven window movement laterally and will overstress the motor.

While im in there do I really need to keep that shitty clear plastic on there?
Also do you suggest I buy just the motor? and then dig into it?
Maybe. The geometry of the window is kind of complex. If you have a mechanical issue with the lateral movement, the window would probably slide to the left/right (instead of down) and then drop suddenly to "catch up" to where the motor wants it to be. Here's a good thread with pics of a potential cause problem: (If this isn't your issue, then you may have another roller problem or something causing the regulator to hang.)

Yes!!! Its your vapor barrier and is THE thing that keeps water from coming in through your door and soaking in to the door panel sound insulation. (Water gets between the window and door, then in to the door, and then in to the cabin.) If its really messy, you can remove the goo from the door (I have a technique to do this if you need it.) and get new vapor barriers from GM with the black goo pre-applied. (I think they are $10-15 a piece, depending on the dealer.)
No, I think its more likely that you have something mechanical amis in your door than a problem with your motor. (I missed the first sentance of your original post and was replying to the second only.) A mechanical issue may also be at cause for the window not going up.
Also, check to see if you have this problem - this could be it also: https://ls1tech.com/forums/general-m...-they-way.html

Well it will or would often go up and down, but sometimes it would stop halfway up. and as it was rolling down the fround would sometimes drop.
I went ahead yesterday, bought a new motor. the window rolls up and down fine now and even seals very nice and tight against the weather stripping.
This is the passenger side since I havent done the driver yet.
I looked over what I could while I was in there. Looked ok visually but I dont know nothing really about it. The window has made several passes up and down and does so fine.
The first 10-20 passes of up and down it would roll smooth each way and maybe 2 of those times it would drop.
It will roll up fine no struggles and it seals fine still but maybe 10% of the time as its going down it seems to drop a little bit.
I guess as long as its now sealing good and not leaking like a german ***** I should be ok right? That was my main problem.
The windows wouldnt roll up all the way and during heavy rain or a carwash they would just pour water in on me.
Other then replacing the motor which I might add that I couldnt really even see to begin with, I dont know anything else that I could have possibly done to make it go over any smoother.
I through the vapor thing in the trash.. Guess I need to dig it out.

Did you use bolts to attach the motor to the regulator? If so, they may be too long and may be hanging up the regulator as it goes down. You can test this by rolling down the window to the point where its been getting hung up and then stop. Then check the regulator arms. If they are near the motor bolts, that was/is probably your problem.
Nothing is hitting or rubbing.. Ill get a video hosted of what its doing. Once you begin to roll the window down while the door is closed the window will roll down normal (passenger window) get down about 3-4 inches then it drops down about 2 inches solid in the front.
Rolls up fine and seals tight too.
when the door is open it rolls down fine. no dropping.
I used the tiny bolts and such that came with it. Put the motor in seated the gear for the motor in the teeth on the sprocket. hooked up all the nuts and bolts tight and then put it all back together.
Makes no sense. Im just happy its sealing all the way. I have video just need to host it.

Ok I got the Driver side done today. Found out why the windows would roll down and "DROP" and not roll up all the way.
It has something to do with the tracks. The windows will roll up and down fine, but the rivets that hold the track to the door itself have worn and are sagging. I had the window propped up and then fully up with the clamp and then I stuffed cardboard pieces under the rivets. Lame attempt to helo prolong my windows. Since im not sure that anything could even be done to fix this?
Anyway, they roll up and down fine. the driverside dosent seal as well as the passenger side because it appears that its dropped down too much.

Are you talking about the rivets that hold the top track to the window glass? If so, that's really odd. A glass shop should be able to re-rivet that for you for very very little money and it will be a lot more solid for you.
Once you have that in, you just have to re-adjust the window to get it sealing right. There 2 top stops bolted to the inside of the door that limit the upward travel of the mechanism.

You know the 4 ish rivets at the bottom of the door near where you drill for the rivets on the window motor? Those are the ones sagging. When you raise it up with the clamp you can see the pressure on those rivets be lifted.
I made some make shift shimms from some cardboard and pushed it up into the bottom of the rivets to give it some extra bite.
Seems to have worked but I know that over time they will wear out.
But my only problem is that the window motor works perfect but the opperation is fucked up.
When you normally push down on the button to roll down the driver window mine now goes up. And when you go to roll up with window. My window now rolls down.
No idea? Is my motor the wrong one maybe I have two passenger side motors?
The connectors are all hooked up right. my passenger window rolls down fine.
Any ideas? My windows actually work now, so im very excited that they roll up and seal and roll down well.

All of a sudden, there have been tons of posts lately about the motors running backwards like this one: https://ls1tech.com/forums/general-m...-opposite.html There are several fixes you can do, but I'll put my money down that the motor is one of a batch of bad motors that have come in to the country.
