I've got a 90 245DL with power windows. All window operate, except the passenger side rear. All the other windows operate at the specific door and at the driver's side main panel. The p/s rear doesn't operate at either location. I have opened the door and examined the wiring, it seems to be ok. I took the switch from the d/s rear(which was operational) and installed on the p/s rear. The p/s rear window still did not operate. Today, I disassembled the p/s rear switch, there was some corrosion. I cleaned thoroughly, reinstalled and window still does not operate. Any thoughts as to the cause?
Looking at the inside of the door, I saw 3 bolts that were holding the motor in the door. Are there any other hidden bolts or screws used to attach motor? The motor didn't drop out when I removed these 3 bolts.
One last item, can I swap the p/s front motor to the rear to test for faulty motor?
Thanks
