The problem: The front passenger power window only goes down and does not come up. It does not come up with either window switch.

Currently, the window is all the way down and I have the interior panel off. When I click up I hear dead silence. If I hit down I hear a faint click that means it would still go down if it could. I have verified that the switch on the door is fine (by trying it out on another door). The wiring that pulls the window up seems to be in place (as far as I can see by looking down from the top and the limited openings on the inside of steel door). I've read about motors and regulators being a problem but I don't know much about them.

Any ideas what the problem is. Is it repairable by a willing, amateur DIY'er.

If I were you, I'd replace the motor. If you've tested the switch and it works in both directions on another window, then you can rule that out. And its a long shot that its just the wire (at least without seeing any significant damage to the wire or its connections to the switch or motor). You can replace the motor yourself if you have the patience. I did mine a while back and getting to the motor can be quite a pain in the you know what, but you could do it.

Thanks for the reply.
I was getting ready to pull up my sleeves and pull the window motor out, but remembered that I'd better check that the window motor was getting juice.

I would have bet a hundred buck that I was getting juice to the motor since it would make a click sound when I tried to put the window down (already maxed out in the down position), but no noise when the pressed the button to bring the window up. After unplugging the window motor plug, I found that I had 12 volts when pressing the window button down and 3 volts pushing the button up.

Wiggled the wires around in both the passenger door and drivers door to make sure the ground wire wasn't nicked or damaged, but that didn't help. Then I decided to check out where the main ground was and decided to clean that up and make sure I had a good contact, so I did that. Then I thought I'd better check the battery. It still had the ford stock plastic covers on, so I pulled them off and found a moderately corroded ground wire on the battery. I cleaned off the wire reallllly well and that fixed it right up. It's weird because the ground should have affected the other doors or starting performance. Regardless, it's now working consistently for a week.

Thanks again.
