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!!!

SOURCE: heat/ac blower motor works on high. intermittent on other speeds.

Check the blower resistor pack - usually located in the heater air ducting in the blower fan airflow. Check for loose connections and open circuit resistors on the unit.
If speed 4 works always, its unlikely to be the blower motor ground connection.

SOURCE: gmc sierra blower switch

last place to look is the resistor block located in the duct work for the blower (fan). it should have a wiring plug going to it and be held in by a couple screws. look on the passenger side near the fan itself.

SOURCE: Blower on heater works sometimes, sometimes it

Sounds like the blower resistor. It will either be located in the engine compartment outside the motor or inside the vehicle inside the blower motor cover. It could also as well be selector switch

Air condition and heat won't work


Check to see if you are getting voltage to the blower motor if you are the motor is bad if not check the fan speed switch. 1 2 3 or low medium high if you get voltage going to the switch but not from replace the switch if you have voltage from switch check the blower motor resistor the although with the blower resistor you commonly have a high fan speed in the max setting and the lower speed settings don't work wich would make you think 1 2 3 are not working but 4 is. That is why it is best to check all parts to make sure the part you do replace needed to be replaced

When the blower motor did work the heat would come out real fast the go really low on the high could it be the blow motor


try tapping the bottom of the blower motor with the key on and the switch set to high. If the blower starts to work replace it.

The air conditioner isnt blowing hard


Do the blower speed settings still work, just weaker? Or is it just one low speed all the time? If you can still change the speeds then it's a weak blower motor. If its just one low speed all the time, (same speed for high and low blower speed settings) then you need a blower motor resistor.

Blower motor only works in hi , was not working at all replaced fuse and got only hi fan


I assume this is the blower for heating and cooling your cars cabin. If so this same problem occured in my mom's 2003 dodge caravan. The reason why the blower doesn't work is because your blower motor recieves a certain amount of power, this power is then dumbed down by a ceramic resistor. if it doesn't work unless in max or high, that means your resistor is broken. the reason why the max or high setting still works is because it does not require a resistor as it uses full power.

Fan only works on high speed not low


Try the HVAC, it is Heating, cooling, AC regulator, located near the blower motor. It controls the amount of voltage going to the motor, the highest setting by pass the restictors that is why it only works on high.

You have a bad blower motor resistor. This is located under the dash close to the blower motor itself

Blower for heater stopped


Remove the hush panel under the dash and unplug your blower motor turn the knob and see if its getting power. If it is replace the blower motor. If your heater seems to work on high but not the other 4 settings. replace the blower motor resistor and pigtail (same general location as blower motor)

Heater blower motor works intermittently


I would replace the blower motor, this sounds like a motor brush problem inside the motor itself.
