My girlfriend came home today and said there was no heat in her pathfinder. I checked it out and there was no fan. I checked both blower fuses and hotwired the blower relay and still nothing. I think I hear the fan turning slowly when the heat is on but if it is, it's not fast enough to throw out any heat. There's also no change when I remove the fuses or the relay. What's the next check?

Hello !

Check the blower resistor and replace it if faulty.

Good luck!

Also check the power going to the resistor
It`s not working at any speed?

No, The fan's not working at any speed.

How do I test the resistor? Do I just test for 12 volts between the contacts?

Thanks for your help.

Hello Again..

CHECK POWER SUPPLY FOR BLOWER MOTOR
1. Disconnect blower motor harness connector.
2. Do approx. 12 volts exist between blower motor harness terminal No. 1 and body ground?

here`s how:
