need quick help with power windows

[bhuff30]

The power windows on my 88 mustang have been acting funny lately. There is an intermittented short circuit, and it appears I have now found the cause. The problem is that the passanger window is rolled down, and the motor will not move. It appears to be shorted out because I get .9 ohms of resistance accross the motor, and when I directly hotwire the motor, nothing moves and my wiring gets hot to the touch (tried switching the polarity, same thing).
Now, I have to figure out how to get the window up! I really don't need to have anything stole out of my car (or the car itself), and we are suppose to get showers and t-storms for the next few days. If I can't get the window up by tonight, I will have to leave it in my parents garage 40 miles away and drive the 90 aerostar.

That happened to me once. I just kept tapping on the motor while trying to push the button to make it go back up and it finally did.
You could try taking the motor apart and cleaning it out. If that doesn't work you will have to buy a new one.

To raise the window for now, just loosen the motor until the gear is disengaged. You should be able to pull/ push the window up. and then tighten the motor back up. It does sound like the motor is bad.

Thanks for the tips. I finnally got the window up by tapping on the motor as 89sleeper suggested. Looks like I will be replacing the motor sometime.

for future reference, what Trbkrb said is spot on (if other alternatives fail). IIRC, there are three (recessed) bolts that hold it in. have an assistant holding the window - it is heavy and will crash down.

someone else once reported that simply moving the wiring harness a little helped it (kind of a goose test for the window motor).

good luck.
