Window Problem

[Quick Pony]

I replaced the window motor (drivers side), on my 1991 LX 5.0 convertible about four months ago. Window worked great! This week when I go to put the window up it stops about 1/2 inch from the top. I can hear the motor when I press the button but won't go to the top. Also the window seems loose when I move it back and forth with my hand.

What could be the problem? Is it hard to fix? Do I need parts to repair?


Thanks

was the motor a remanufactured one?

Sounds like its part Adjustment or Replacement Time.
Which parts are hard to say with that info.
Could be window bushings, retainers, rod locator, grease, motor alignment, drive gear.
It just sounds like something is loose or wore out. With out taking off the door panel and digging in there, hard to guess which it is.
It does sound like the motor is Still working, at least so far. Dont over do pushing it, they are not THE best in the world, and can be burnt out if pushed.
It all sounds mechanical at least, For a change. I have been reading A LOT of electrical door problems lately.

I purchased one from Autozone. It cost me $70.00, so I guess it was a remanufactured one.

Check the warranty. If it is still under warranty, swap it out.

If not, then...

Motor removal & replacement
Remove the door mounted speaker & the upholstery panel to gain access to the motor. There are 3 screws (5/16" hex head, I think) that secure the motor in place. Remove them and the motor comes out without any problems. Once you remove all the screws from the motor, and it falls away from the gear teeth on the arm for the glass, the glass will move up and down. You may need a helper to hold the glass once the motor screws are out, since the gear on the motor holds the glass from sliding up or down

Motor interchange
The motor is the same for left side or right side, only the gearboxes are different. If you can't find the complete assembly for the side you want, you can get either side and use the old gearbox on the new motor.

The window motor gearbox has 3 plastic rollers that are a safety clutch to prevent possible injury if the window is rolled up while something or someone is hanging out the window. The plastic rollers will often disintegrate into chunks of plastic and the window will no longer roll up or down. The motor runs, but the window does not move or only move a lttle.

The Help! section of your local auto parts store will have the replacement plastic rollers.

i think autozone has lifetime warranty on most of there stuff. i would try to take it back no matter what. just tell em that its broken, i doubt the will question you, then you can eliminate that problem,

but more than likely the plastic bushings are broken or about to break

Just to be sure, put a light coat of grease, Vaseline, or even wd-40 on the tracks. On my '92 Olds, I had rust, then crud build up to such a point where it was nearly impossible to move the window. I was "sure" that I'd have to replace the tracks and the rollers. Nope! It was just rust and grease build up.

If you're near the shore, you may have slat build up inside the tracks along with grease and crud.

It's simple enough to check and do. And, it's better to make sure that crud build up isn't the problem now, instead of buying new tracks, motors, and taking the door apart.

Anyone want to buy a brand new '92 Olds window crank assembly? Hey, at least I didn't buy the driver's side assembly also (which was in even worse shape).

Also, make sure that the rollers aren't worn, and the tracks aren't bent.

Yea, chances are it's the cheap autozone motor. But, it's free to do what I suggested above.

IMHO, regardless, you should upgrade to a '92 Olds crank assembly! I have inside info on where you can get one cheap. Plus, the '92 Olds window crank assembly is 0.000001 ounces lighter. So, your quarter mile times will go down by at least 12 seconds, your gas mileage will be better better than a Pruis, and all the chicks will throw themselves at you because you're so smart!


BTW: Yes, the world is coming to an end. I passed up an opportunity to say that Autozone sells cheap cr*p and they suck. Oh wait, I just said it!
Never mind then, the world isn't ending.
