Well, I thought I would share my window problem, my 94 convertible came with a window problem on the passenger rear and I thought when I bought the car that it was probably the window motor and I was wrong, the window motor and window switch were good, after some research I found that it was a bad wire and that the wiring coming out of the door before it goes into the body were known for problems, it was easy to find once I moved the rubber grommet out of the way
if you found the wire then fix it and it should be good. Wasn't aware of any regular problems with the windows.
the 5-wire system they use to drive the door locks is one of the more difficult to trouble shoot what is wrong. How did you determine the motor/switch were good?
well then if the wire, switch and motor are all good then I am at a loss as well. What happened when you swapped motors and this is all assuming that your test light showed there was power at the motor?
I fixed it, it was a bad wire between the door and the body , I was just letting people know what I found out
