If you are getting power at the fan plug, it is possible that the recycled motor is bad.

My 2001 Nissan pathfinder heater will not turn off. A/c worked fine and did come on one time when tryed but the heats up now at any setting and is extremely hot.


There are three culprits that may cause this.

1:Many people have great luck with replacing the resistor unit for the blower motor. While I cannot guarantee this is the issue you have, it is the most common. (Approx $45. )
eBay link.. http://www.ebay.com/itm/Heater-Blower-Motor-Resistor-For-Nissan-Pathfinder-Xterra-Titan-Pickup-Truck-/131110853460?hash=item1e86d0db54&vxp=mtr

2: Others have luck when replacing the actual Plastic switch inside. This runs about $50

3: Then there is the blower motor amplifier.. (approx $110)

Your service manual will show location of these items or a quick search online for schematic for your model will produce results to assist you from here.

Hope this helps.

Blower not working. How to test


if the blower is working when you jumper it at the motor you`ve eliminated the motor itself.if you have replaced the heater control with a new one or known good used one then the only thing is the blower motor resistor has gone bad.i`m surprised you did not check and replace this unit after jumping the blower motor.

Ac/heater fan doesn't work


According to my wiring diagram, the blue and white wire from the blower motor gets power from the key switch. The fan switch and resistor grounds the motor.
No blower fuse is listed.

Heater / air conditioner fan control doesn't engage fan. Previously, it only worked in high speed.


I would replace the blower motor resistor first then see if that corrects this. The resistor is located next to the blower motor under the dash.

Where is the fuse to the heater fan blower located in my 2005 Pontiac Grand Prix. Owners manual has 3 different fans. Is it the HVAC fuse or one of the 3 fans? The heater fan quit and want to check the...


Hi, should be listed as heater blower motor not fans ,the fans is the ones in front of radiator. most common problems are the blower motor resistor, which is in passenger side compartment near fire wall.This is were your blower motor is also. You can check and see if its getting power to resistor, with a test light if power is at resistor, check and see if you are getting power at blower motor if no power there replace resistor. But if you have power at motor replace blower motor. If i can help further just re post. thanks

Ford explorer heater fan not working


If this occurs in all positions, check fuse, check for power at the fan motor, if power in all positions replace motor. if no power at fan and fuse is good, check blower motor resistor and blower motor control switch. Replace as required

Subject: 2004 isuzu rodeo...my ac/heater blower is not working


The resistors are in circuit only on the lower fan speed settings.
On the highest speed setting, power is switched directly to the fan motor.
Check fan power supply fuses,
Check power is available to the fan when high speed selected.
If all above OK, apply power directly to the motor to verify fan motor runs- if it doesn't the motor may need replacement/repair.
