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.

Location for blower motor/heater/fan fuse?


Before you rip, check the 30A HEATER CIRCUIT BREAKER in the instrument panel fuse panel. The input is hot with the engine running. CB output connects directly to the heater blower motor. A cluster of heater blower motor resistors determines blower speed as selected by the blower switch in the heater control assembly. The switch setting is sent to the powertrain control module (PCM) which acts to turn the blower motor on at the selected speed.

The heater fan isn't working, on any setting, on my 2004 cavalier


You will need to replace the fuse located underneath the drivers side steering wheel. Flip the fuse box cover lid over and you will find a diagram showing where the heater blower motor fan is located. Pull the fuse out and replace it with the same number fuse.

My air conditioner/heater blower will not work on the 4th setting. Setting 1,2, and 3 do work. I have replaced fan speed switch and replaced the resistor. Any ideas?


You'll have to find the correct wiring diagram in order to trace down the fault in your system.. Once you obtain the wiring diagram you'll be able to see what else beside wire is between the #4 speed setting and the blower motor. My guess is you might find a high speed fan relay is triggered from the #4 fan switch setting, applying full battery voltage to the blower motor. If locating the appropriate diagram proves to be difficult you can try looking around the underhood and passenger compartment fuse panel to find a relay. Keep in mind not all relays are always in fuse boxes which makes the diagram important.

Need to replace ac/heater fan resistor I am not sure of the location does anyone know? Thank You


The Blower Motor Resistor is located on the passenger side firewall, not far from your A/C's H-Valve (or expansion valve), going inside of the vehicle. The blower motor resistor has a 4 or 5 way black connector plugged into it and this is the only visible portion of the Resistor you will see. Remove the wiring connector and remove the 2 or 3 screws with an 8 mm or 5/16" socket (8 mm and 5/16" are the same). Once the screws or fasteners are removed, just pull the blower motor resistor out of the firewall and if you look at it, it will have various coils of wire on it, sometimes it will show burnt coils, but you can always check the various coils with an Ohm-meter.

Aside from that, install the new Blower Motor Resistor and Voilà! Your inside Blower Motor should work just fine.

A brief note here, if your fan doesn't work when the fan switch is on High, then it's not the Blower Motor Resistor, but possibly the Blower Motor itself. Should this occur, please get back to me insofar as how to replace the blower motor and why the blower motor's wires have to be twisted...even with the new blower motor fan.

Best of Luck,

1998 Ford Contour. The heater blower stopped suddenly. I checked all the fuses, good. I removed the blower and hooked it to 12 volts. Whoosh! It almost spun out of my hand. I checked the plug into the...


I dont know what these other guys are saying..I think they snif the glue!!! YOUR BLOWER FAN ASSEMBLY CAN EASILY BE REMOVED !!
1. Remove the wire
2.Find the "tab on the housing and pull it down while rotating the fan housing counter clockwise. This will remove the fan assembly. Plage 12 volts on the contacts to test the motor. If it works then the resister pack is blown. On the fan housing (near firewall ) you will see a plug going into a square looking box with a screw in it. Remove the wire then remove the screw to remove the resistor pack.. A new resistor pack is around 20 dollars at a ford dealer. Hope thie "FREE" info helps!

Heater blower for front heater doesn't work, back one does


First: check the Front Blower Motor Relay located in the IPM. Its' location should be on the back side of the cover. There should be an available Spare Relay. Replace and Check operation.
If this does not solve it.
Try the Fan Speed on "high". If the Motor comes on only "high" and no other speed, then it is definitely the Blower (Fan) Motor Resistor and must be replaced. It is located behind the dash Glove Box. Remove the Glove Box. The resistor is located on the back fire wall, and has 3 to 4 wires going into it. It is approximately 3 1/2 inches wide by 1 1/2 inches high. Disconnect the electrical connection. There should be two bolts (I believe 8mm) holding the resistor in place. Remove the bolts and Remove and Replace. Check the operation.
If this does not solve it:
Pull the connection to the Blower Motor and check for Voltage with the Fan On "low". If correct voltage: the Blower Motor itself needs to be replaced.
Let me know if this helped; or if you have additional information or questions. Feel free to contact me at FixYa.com!

Jeep Wrangler Heater Fan


First, check for power (12v) at the fan plug. If you have power, the fan motor is shot. (replace it).You can "hotwire"the blower right to the battery to verify motor failure... don't forget the motor housing needs to be properly grounded or power is useless!!
If no power, check the blower motor resistors (located on the firewall side of the heater box... usually looks like an oval flat plate with three or four wires connected to it. When removed, you will see two or three small coils: they should not be broken. Upstream from that you may need to look at the blower relay. Generally by the time you get to that, you have already solved the problem. If not, get a good wiring diagram before going further!
