My driver side rear window assembly and motor went or so I thought. I replace the whole assembly and motor and now it works fine. When I pulled out the old assembly it looked like the assembly was find and I believe it was just the motor.
2 weeks later my rear passenger side window wont roll up but will go down. If I dont have to I dont want to replace the whole assembly, just the motor. How do I know if I need a new motor or a whole new assembly and motor????
