I am pretty sure that the switch is okay, as I took it out and swapped it with a working switch, and the passenger side window still would not come down.

I haven't gotten around to this yet. I did buy a set of window hardware.

The local guys (Finish Line here in Miami) tell me that a new window motor will cost me $85 plus tax. But I am guessing that it is simply something stuck or broken, since the window went up and down rapidly and smoothly with nary a groan or squeak.

I have never peened anything. I am a novice peener.

Must I peen this on the car, that is, sideways, or can I do my peening on a nice, flat surface?

Where can I find rivets for some practice peening?
