Headlamp motor problem (89)
I have taken the headlamp motor apart, because the motor runs on, and runs when you connect up the battery.
I thought it would be a bushing problem, but the bushes are brass and seem fine. So I have greased and reassembled the motor and tomorrow will refit it. My question is, what causes the motor to stop running in a good unit. Where is the voltage unapplied? (if thats a word)
In short, how is it supposed to work?
If I know that I may have a chance to fix it.

Three relays on the drivers side front wheel well under a cover ( on my 86 ). You can switch them around (they are all the same) to see if thats the problem with the one motor. I think the relays are about 15 or 20 buck at the chevy dealer.

OK, - well I'm screwed on this one, Gonna take the good one apart to see if I can learn something. Not yet though, this is a seriously damaged car, (not mine) - I'm gonna stick this problem on the backburner for awhile. Plenty more stuff to fix.
Thanks for the help though, I have bookmarked the thread and will come back to it. Thanks all for your contributions.
