Hi,
The power window in the left door of my 82 doesn't work. The window will not go down when the switch is pressed, but you can hear the lift motor running and a slight "ratcheting" sound. If the window is pushed down by hand, the lift motor brings the window right up. It seems that a gear is stripped, but how does the assembly come apart?
Thanks,
Tom

 

You're going to need the AIM and chassis and service manual for this repair. Be extremely careful when working with door glasses. They're heavy and the punched hole edges in the doors are sharp. You could chop off a finger if that door glass falls. Go slow.

 

Completely
This an area you need to be very careful if you have never done this.The scissor of the regulator arms can get you bad as soon as you remove the motor.At the age of 16 I got stuck in the door of a Thunderbird for an hour until my neighbor came to my rescue,lost a lot of blood and have the scar to prove it.I use rubber coated clamps to hold glass up.
EDIT-Like to add put a bolt in center of gear (head towards outside of door)also,when its loose from glass the spring can get you too.

 

Tom,

Its not hard but first time doing it will be a bit of an experience.

PART 1

Take off the the door panel. Remove the cover over the window motor at the bottom. Is the regulator still held on with rivits? If so you will have to drill out the heads and pop the rivits. If the rivits are gone and replaced with bolts its been out before. If not you will need to replace the rivits with bolts and a lock nut on the back side on reinstall.

PART 2

You can take the glass off and out or wedge something between it and the frame to keep it in the up position. I did the wedge thing.

PART 3

Undo the two bolts that hold the glass to the regulator.

PART 4

The part of the regulator the window was attached to is also attached by way of two rivits or bolts to the door frame. Remove them.

PART 5

Now that you have the bolts or rivits all removed. the regulator should be free. Leave the motor in. Use your power window switch to power the regulator down. Compress it. You may need to assist it since the gear is stripped. You need to compress it to pull the assemble through the access port at the bottom.

EXTRA PART

If you find you cant compress the regulator electronically because the gear is stripped you need to remove the motor. BUT once you remove the motor the spring will cause the regulator to collapse. Watch your fingers. Most inset a bolt into the the regulator to keep it from collapsing. GM has a spot for this bolt. The problem in doing this way is if the bolt keeps the regulator from collapsing enough the assemble will not fit through the access port. You will need to play with it.

Once out you can either rplace the regulator or repair the gear (there is a part you can by to do this).

Install it in the same fashion. Use bolts with lock nuts in place of rivits. Get bolts long enough for the bolt to full thread but no long enough to obstruct. Bolt the bottom part on. attach the electrical. Power the regulator up. Slid the bar over the roller on each side of the window. attch the bar the rollers are on to the frame again.

Its not as hard as it sounds a visual will show you that.

Very good outline supplied by JDP6000

 

But I would use something more positive than a wedge to hold the glass.

 

Thank you for the replys.

Tom
