Window motor or some other issue?

**Dewman** · 07-30-2010, 09:09 PM

I searched but i could not find a exact answer. Recently my car has developed a problem with the passenger side window. It will only roll up/down in couple inch increments if i allow for about 30 seconds in between each attempt. This sound like a motor issue or something else?

I've been having the same issue with my drivers side window. If i help pull it up with my hand it will go up fine, but if i stop, it will stop itself half way up. the car only has 34k on the odometer, so i didnt think that the window motor would be done already. i read on here somewhere that the windows are way under powered, theres a website posted on here somewhere that makes a kit for it. Would love if anyone else had any suggestions............have a baby on the way so I'm kind of on a tight budget.

Yes it's a window motor. My drivers has been doing the slow roll for a couple years now, I guess I'm just lazy and won't fix it until it gets worse.

And DaddysZ28, congrats on the new addition!

Window motors for both situations. They're good for about 2 years at a time with normal use. I don't think it is so much that the motor is under powered as it is the glass is huge and heavy.

There used to be a sticky for this fix...

Advance Auto Part sells window lift motors with a lifetime replacement warranty. I've taken advantage of that more than once.

I have had to replace four (motors) of this type in three differant cars (all F bodies) Third gen and forth gen. Seems to be a GM issue. The first time you change the motor it's a little difficult because you have to blindly drill through the door inner panel to get to the rivits holding the motor to the regulator. Once you have that done the rest is a piece of cake. Motors are made to fit either side, and they are not that expensive (under thirty bucks)

This is one of the inconvieniences of owning a F body car....Good luck

Autotrix (site sponser) has an excellent fix for a reasonable price..

Side note: The sooner you guys stop closing your heavy doors by grabbing the glass, the less problems you'll have with motors and regulators.. My Camaro is now 9 years old and still has the factory reg's and motors and yes they still work...just my .02

i dont use the windows to close the doors

car was built in 99 so 11+ on stock motor/regulator

(plus its my passenger window i am RARLY opening that door)

Dewman, I agree with you I don't use the window to close the door either, also it was the passinger side of mine also. I use just enough push to close the door and that's it.

I don't know why they crap out but, it's not that big of a deal to replace anyway.

Hi all,

I had problems with my power windows. The driver side window had stopped working, and the passenger side, would go down normally, but go up real slow. I replaced both window motors! The drivers side works perfect, and the passenger side is exactly the same! Goes down quick, normal, and goes up real slow and at times stops! Any ideas what else it can be?? since I changed the window motors, as well as the window switches.

Thank you!!

Autotrix did the job for me. Both windows were slow going up and after the install both are much better - better than when the car was brand new. I never have replaced the motors.

There are many people that have installed our kit on original window lift motors on their F-bodies and are still driving them with zero window problems.

My wife still drives a 96 T/A with 207K miles and the window motors are original and fully operational.

So I bought the window kit for the passenger side window in August, I got it and installed it back then. Posting videos now, window works great!!

I'm finally posting the before & after videos!

im having trouble with my driver side window only going down half way and then it stops working. and if you give it five to ten min it will roll up or down an inch or two and then stops again... is it for sure the window motor or is it something in the wiring?

**gnomee** · 10-20-2010, 04:56 PM

98% its the motor. VERY VERY VERY rarely the express down module will die and cause this issue.

If you want to rule that out, it is easy to bypass it and see if the window works.

Go here: http://www.autotrix.net/install/

ON the left you will see Driver Side Express down. Click that then check out steps 19 and 20. That will help you jumper the plug once the module is removed.

Personally I would just replace the motor though.

Installing our kit on the passenger side will put both motors on their own circuit and help with premature failure.

Also make sure you grease the regulator real well when your in there.
