I had a window stop closing at the worst time. I was 1600 miles from home, without a meter or toolbox and, since I would be entering and leaving a parking garage daily (in Houston, in August), I NEEDED the driver's window to work.

I felt lucky when I found out a parts house could sell me a rebuilt motor/operator; not so lucky when they said it would take about 2 weeks to arrive.

I pulled the door trim thinking I could operate the window manually until the part arrived.

What I found:
The motor, wiring and switch were fine, but the shaft of the large, nylon worm gear was frozen in its housing. I was working in my brother-in-laws VERY poorly outfitted garage. He's a concert grade pianist, so you cam imagine what I had to work with.

Having nothing to lose, I hammered the worm gear out of its housing. I found a cheap twist drill which was about the same diameter as the gear shaft. With the drill drenched in PB BLaster, I worked the shank end back and forth thorough the hole, hoping to clean away the corrosion without resizing the hole (too much). It worked! I think the burr around the lettering on the drill was just enough to "mill" away the caa-caa.

Once I had the worm gear spinning like a well-oiled German sewing machine, I treated everything to some fresh white lithium grease. I think I impressed The Impresario when I cut a new gasket out of an empty cereal box.

Now, 9 years later, that window is still working, as Gen. George Patton might say, as slick "as shit through a goose".

That's my experience,
