Nissan Repair Questions? Ask a Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question.
Ok, first, you can only check when it is not working. If it is working at this point, nothing will show bad. When not working, check for 12v in both directions when operating the switch. If 12v is present, then replace the motor. If not present, then test for 12v at the switch on the wires going to the motor. If not present, replace switch. If present, then repair wire between switch and motor
