Sorry this is giving you so much trouble.

I had no difficulty removing the motor. I suspect that this was easy for me because I had a new motor to look at and could see where all the conections were, but if you unbolt all of them (there are three or four bolts at most), it is quite easy to remove, other than unsoldering the electrical connector. All I did was pry it out a bit and twist it gently.

As I recall, when I hit the switch and the window did not come down, it make the courtesy (interior) light dim a bit. That is how I knew it was not the switch. If it had been the switch, there would have been no electrical resistence and no dimming.

My switches seem to be interchangeable, if you line up the hot wire and the ground in the proper positions. I seem to think that some plugged in backwards. But there may be a difference between my 85 and your 79. I know the door lock vaccuum pods are different.

When I went to put the motor back in, I recall that holding the bolt or nut (I forget which) in position with a magnet proved helpful.
