Nissan Repair Questions? Ask a Mechanic for Answers ASAP
The best way to figure this out is with a test light , unplug the blower motor when it stops and see if it has power and ground at the plug, If it has power and a ground on the other wire, the motor would be bad. if not it could be the resistor or the controller going bad. Let me know if you have more questions, ROY!
I do not know how to reach the power connector on the blower I would appreciate your guidance in in accessing it. Also but when I took off the resistor., I tested the following:
With ignition on, and fan speed selector knob on max, I checked the power on the plug. The plug had power only on its first pin the other three pins had no power. When I try to attach jumper wire between the first and any other pin, the blower still does not run, does that mean that the blower motor itself is bad?
Where is the controller located and how can I check it?.
here is the inspection for the resistor, I would start here, Thanks ROY!
If the resistor is grounded it will be max speed, it grounds through the switch here is the electrical pic. Thanks ROY!
If you ground the blue and white wire at the resistor the motor should run, if not the motor will be bad, if it works then the switch would be bad.you should also have power at this wire. the motor will run with the resistor unpluged if the switch is in the number 4 high position. this is a direct ground for the motor. let me know , ROY!
You do not want the blower motor to be bad you will have to remove the complete blower box to get to it, Thanks ROY!
I am glad you figured it out, and Thank you, XXXXX XXXXX Accept, ROY!
