When I bought my car my window motors weren't in the car, so i finally got around to getting new motors, and i went to put them in and checked to see if they'd actually work, on the driver side they don't, but on the passenger side they do, I checked the actual switches to see if they were dead, one of them was, while two still worked, so i put the two in that worked on the driver side and it still doesn't work on the driver side, i'm thinking its the part that the switches connect to, but i'm not 100% sure any ideas?
