Hi guys, my drivers window won't roll down so I took the motor out of the door and it will roll up but not down, any ideas?
I put power to the side of the connector that gets juice to let the window down but I don't think that proves anything (It didn't actuate the motor either).

Do I have to use the other wire as a ground when I do this test? The other wire is the one that reads 12V when the switch asks the window to go up.

Is there any way to clean or repair these motors?

Do you have a copy of the FSM? If not, download one from either of the following links:

Section 15, pp. 36-37 show how to troubleshoot the system. Since the window works in one direction but not the other, the fault will usually lie in the switch itself. Those can be taken apart and cleaned, paying attention to burnt contacts. If the switch is beyond repair, post a WTB. Somewhere there is a writeup on how to install relays to help prevent further burning of the contact points, the most common cause of switch failures.

I'm not 100% sure on this (so wait for more responses to confirm), but I believe if you put positive to one contact on the motor and negative to the other, it will go up. Switch them, and it will go down.

The switches themselves can get finicky though, and I wouldn't be surprised if it's an issue with the switch (and not the motor). One way you could tell (without pulling the switches out) would be to disconnect the wires from the motor, and use a voltmeter/multimeter or test light to see if they're getting power when you push the switch up or down. Otherwise, you can take out the switch, disassemble it and clean the contacts. I'd bring the switch indoors for this though - it's been a few years since I've done it but I seem to remember a few small parts inside.

^Exactly right. Swap terminals to go in the other direction. As already mentioned, switches are usually the problem. You can take them apart and clean the contacts.

+1 just clean your switches, its very straight forward, and i think that there's also a thread about it, give me a sec see if i have it bookmarked

while you're at it, you should take the door panel off and re-grease the rails, what i did cuz i'm lazy was just put some grease on my hand and feel around the rails, make sure you cake lots of it on there then roll the windows up and down a couple of times. or you could take the window off and then take the rails out too.
