Hi guys, first post here.

I recently picked up a '99 GTP and one of the issues I'm having is with the rear driver's side window. I picked up a new window motor from Rock Auto, assuming it would be the problem, but upon plugging it in I still got no response. Then somebody told me that the windows operate on a loop system from the driver's control switches and that I should try swapping the switch out. So I went to a junk yard to pull another one. Lo and behold, it operates all windows... except the rear driver's side.

Any suggestions on how I can solve this?

Thanks people.
