Where are fuses for heater blower in 2005 envoy

SOURCE: 2005 GMC Envoy SLE blower fan speed #5 is not working

More than likely this should just be your resistor. You have different sized coils on the back of your resistor for all the different fan speeds. if one of them burns out or breaks then that certain speed will not work.

the blower is on a different fuse than the heat deforst one if the resistor is faulty the fan would run on speed 5 only so still could be fuse or motor check for power to main motor under glove box ??

SOURCE: 2005 GMC Envoy. Blower will not work all fuses

all speeds??? could be resistor pack or the blower itself. rap on the blowe and see if it tries to run, if it does, replace it.

SOURCE: the fan to the heater does not work, even on hi

check power to the fan motor

If this a manual HVAC system, the blower motor resistor pack is defective or the blower motor itself is bad.
If this is the Automatic digital HVAC, the blower motor control module is defective or the blower motor itself is bad.
