Replacing a power window motor
Greetings... my car was delivered to me today, and much to my dismay, my passenger window was rolled down. I hopped in, she started right up, but when I pressed the button to roll up the window, I noticed my battery gauge show that it was trying, but the window did not move and no noise was made. I tested my driver's side, and it worked properly.
A few months ago I noticed my window having trouble going up and down, and after 30 years, I just assume the motor is shot.
Is there anything special I need to know about replacing the motor? I see some window motors for r/h on a 75 on Ebay, but are there any special parts I need, or is it a direct swap?
Any tips?
Thanks!
Anthony

Someone will chime in here I'm sure on this...but i can't remember if the battery gauge will show any activity when the power window switch is bad. I replace the switch on my Mom's 'Vette back in '83 and I can't remember. It was an easy fix though if that's your problem.

Try closing the door while you are operating the switch. The window may just be stuck. The ammeter moving says the motor is drawing current. You may have to close the door with a little vigor to un-stick the motor...G/L

I opened and closed the door a few times, tried with the door both open and closed. No sound or movement what-so-ever, but I did get a small dim on the interior lights, so it is drawing power.Anthony

I am at work, or I would look into the hanes manual and check myself

It's not in there.

By the way, by "both" I meant that there's grease on the tracks and rollers and grease in the gear housing attached to the motor. And it was all totally dried up on my car.
I hit the tracks and rollers with degreaser, scrubbed and cussed at them then relubed with white lithium grease. Then I opened up the gear housing, wiped out all the old grease and repacked with wheel bearing grease. Now my windows fly up like you wouldn't believe.

Just wanted to say thanks for everyones help. I am glad I didn't waste my money on another window motor.
I took apart the door, removed the motor, greased the rails and gears, gave it a good knock or two to make sure it wasn't stuck, but it back together...
It worked!
Thanks 'vette forums, you saved me again!
