Crazy Driver's Side Window

[91 LTD]

So out of the blue my drivers side window (never had probs. w/ before) just quits in the down position. I get it to work again and me being an idiot decide its fixed so of course when it quits again its in the full down position. Some contact cleaner later and it seems ok. My question is would just one switch on the driver's bank fail or is there a bad connection somewhere? The window works fine when the switch is functioning. I guess if the prob doesnt resurface it was dirty switches. I did hang my cupholder over the switches (not anymore). thx

I'm thinking switches. I have some switches in GL that do the same thing, sometimes they work, sometimes they don't. Most of the time it's either the switches get contaminated with coffee or whatever, or they are just worn out and the contacts have carbon buildup preventing good contact.

Not working again, whatta pita.

Window works, window doesnt, window works, etc. Once it seemed like working the power lock actuator "cured" it. Loose connection at motor? Also it only seems to get stuck in the full down position. Annoying.

its probably just worn out... when the brushes wear out any little bulp will make them jostle in.out of place enough to work/not work.
try opening and closing the door a few times next time it gets stuck, then replace that motor!!!, or, if you are junkyard savvy, you can pull brushes out without reomving the motor from the door.

I have a thread with details if you like

Love to see it. Thankfully LA is filled w/ electrical motor repair places. They'd have brushes right?

If the rebiuld shop does more than alternators and starters they should... I tired to go to a place that just did those and he said window motor brushes are way smaller... so if they do small motors it should be gravy.

Thanks, prob coulda found it myself, hafta look harder. The rebuild places are run by our friends from south of the border they fix everything.

Sometimes the brushes aren't gone, but the commutator is just dirty. Might be more expensive than its worth tho. Found some cheapie motors on eBay, 3 of the 4 were good, one was just a POS that I gutted for parts to rebuild the original motor. Win some, lose some.

What's a commutator?

this thingie



My drivers side motor froze today as it started raining... I had to take off the door panel and tap on the motor to get it up.... I guess thats what I get for putting used brishes in it lol
Im going to try some rebiult motors from fisher or napa for that and my LR doors...

The copper part on the back of the spinny bit there at the bottom. Its what the brushes contact.

Im pretty sure then w/ all the elec. motor places in LA I can get mine fixed cheap. In Cuba you can get a disposable lighter fixed and refilled, and that spirit (which I LOVE) is alive and well here.
