I just bought one for my 2002 Pathfinder for $140 at a local dealership. It is Crown Nissan in St. Petersburg, FL. I saw it for a little over $100 (after shipping) on some nissan parts sites but decided to get it locally in case I had a problem.

Blower motor will not shut off


I can't speak to the cost, a local dealer can do that. As for the reason the fan runs on, it sounds like either a stuck power relay (location should be in the owners manual) or a bad fan speed regulator. Since the fan is stuck on high, I suspect the fan speed regulator is bad. On some cars the regulator is part of the fan assembly, and on some it's separate. Also, there is a possibility you can repair the circuit board, assuming it's something as simple as a burnt out diode. Best of luck!

Blower motor doesn't work, how do I find out if its the fuse, relay or if the motor itself is shot? I know where the fuse box is but some of it is abbreviated and I don't know what some of it stands for....


The blower motor can be tested by removing the lead to it and seeing if it has 12 Volts by observing if the 'test light' lights up when the dash controls indicate that the blower motor should be operational.

One can test the fuses by using a 'fuse tester' available from Walmart or an auto parts store which will light up when an energized circuit has a blown fuse.

The blower motor is located on the firewall on the passenger side, in general on GM cars from the 1990s.

You may have to remove some items to get to it, though.
Blower Motor REMOVAL & INSTALLATION
  1. Disconnect the negative battery cable.
  2. If necessary, tag and disconnect the number 2, 4 and 6 spark plug wires from the ignition coil and move the coil out of the way.

  4. Detach the electrical connections from the blower motor.

Follow-up


That's why I said to bench test the motor/put 12V to it to see if it comes on, BUT you told me that you have power at the connector, which should turn the motor on, but you have only 2.4 V going in. Since you have the AUTO A/C I would look into the blower motor AMPLIFIER mounted behind the glove box on the side of the air box. Its attached with 2 screws. I would look at that next. Your AUTO A/C setup has a "blower motor resistor" and an "amplifier". Check the AMPLIFIER next. Usually when the RESISTOR goes bad, the blower will only work on speed #4/HIGH, but your doesnt work at all. I would look into the AMP assembly. I don't think that the piece is that expensive. $100??? Good luck and let me know what you find.
