It could be the thing that we call resistor block.
it is the one that controls the speed of your blower. it is located at the engine compartment, near the blower assembly. please check it.

and if you have more concern, kindly use the ask me button,

tnx 4 using fixya,

Hi,

Your concern could be interpreted a couple of ways:

  • if no fan action on any switch/speed setting, then possibly fuse. relay, switch, motor;
  • if some speed works but others will not, then possible the resistor(s) that divides the voltage and provide variable speed to the motor.
If you are considering a DIY (do-it-yourself), your best tool would be a VOM or DVM. You can start with:
  • 40amp fuse in the fuse panel near the brake pedal;
  • high/lo speed fan relays (in the relay bank/main fuse bank under the hood);
  • the resistors, the switch;
  • and finally the motor. I was made to understand that there were issues with water getting inside the blower motor on some versions/models. You may want to investigate that further.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

If the cables, fuse, and wiring are ok, check the switch, and check if the voltage at the switch is correct. If the switch is ok, then you have to replace the motor.

Check the fuse relay if it's blown. Also the wiring from that motor.

SOURCE: The heater / ac blower

It is the blower resister. I purchasted one at auto zone for $18.00. It is located under the passenger side dash. You need to remove the glove box and the plastic cover under the dash to expose the blower motor. the blower motor resister is right next to the motor. Simply unplug the resister remove the two screws and replace. I did this and now my fan works on all speeds.

I would Replace the blower Resister aka temperature heater fan resister.

The motor is fine, the blower resistor is the most likely cause. All fan speeds except high go through the resistor.

SOURCE: Fan blower motor

The Canyon has an inherint problem with the Fan Power cable being loose. When I say loose...I'm saying that you need to adjust the wires and then take a zip strip to tighten it up.

Passenger side under the dask are 2 cable hook ups. the one on the farthest right (Only 2 wires going to the plug) is the fan power cable. Jiggle it while the fan is on position number3 so you can hear when it comes on!!!

Heater ac panel


There will be a high blower relay and resister made together ,this is located very close to the blower motor,it mounts on the out side of the blower case,but actually goes inside the blower motor case to stay cool.This is more likely the cause of your problem.

Blower motor only works on high


The blower motor only working on the high speed setting is caused by a failed part called the AC blower motor resistor, this resistor is located next to the blower motor and one engine goes into the air duct work of the AC/Heater and the other has a large electrical connector going to it.

AC only work on high speed


If the blower motor only works on the high speed it most likely needs to the blower motor resistors replaced. Sometimes when replacing the resistors the dealer recommends that the blower motor be replaced in conjunction. It's believed the blower motor burns out the resistors. The resistor pack is either in the engine bay mounted on the heater box or under the passenger side of the dash board.

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.

Hi, sounds like your blower motor resistor needs to be replaced. If not the resistor, check the blower motor.

The front heater/AC blower motor works only on high


The high blower relay works so the resistor may be the problem
