Yes, that would be the first thing to check. If the fuse is OK, then possibly a short in the circuit. If a short is not found through multimeter testing, then your blower motor is probably toast.

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.

SOURCE: 2005 GMC Sierra 1500 - heater blows, but only cold air

Check coolant level. Check for heat at the heater hose going from water pump to heater core at firewall. Check to see that cable is moving coolant control valve from the closed to open position. Low mileage so it shouldn't be plugged heater core.

Testimonial: "You were absolutely correct. Low coolant level. Put in some 50/50 and we're nice and toasty now, but need to find out why coolant was so low. Thanks."

SOURCE: 2005 GMC Envoy XL High Speed Blower not working

if the other speeds work it is probably the blower resistor; if applies varying resistance to the voltage running the blower; this allows the fan to run at different speeds; should be located very close to the blower motor; behind a panel under the passenger side of the dash

SOURCE: FRONT A/C BLOWER MOTOR NOT WORKING ON 2005 GMC

First check and see if you have voltage at blower motor with key and switch on, with test light, if you do have voltage, blower motor bad, replace it, if you don't have voltage at blower motor, next to it, is where the blower motor resistor is at, follow the wire from the blower motor to it, check voltage there, should have voltage, if you do replace blower motor resistor, resistor cost about $45.00 at auto parts.If I can be of more help. please let me know.

GMC 2004 Envoy blows heat even with blower off ... Why ?


The relay in your blower motor is stuck on, there is a TSB for this issue. Replace the blower motor resistor and you'll be back in business.
How does the resistor get power if the fuse is pulled?
Replacing the resistor will cure both problems. TSB is a technical service bullitin seen below

Blower motor not blowing


Might be the Resistor pack located close to the blower. It has a flat connector with 4 or 5 wires, and two small screws holding in the duct. It may be a crispy critter. It happens... The blower moves air across it to keep it cool. The blower motor may be bad as well, or possibly the fan speed switch. May very well be the fuse for the blower as well. The blower connector may be loose. Let me know what you find.

07 gmc envoy denali ac stopped blowing air, replaced the blower resistor but now still no air comes out, like no powere through... so what next, what module needs replacing?


You have three possible things left, check fuse #35 in the underhood fuse panel, wiring harness going to resistor pack (look for burnt wires or melted connector), or a bad blower motor.

ck at the blower motor to see if it is getting power, ck for burnt wiring, also ck the blower resistor to see if it is burnt if so you will need to replace blower resistor and connector.

2005 GMC Envoy. Blower will not work all fuses have been checked.No heat or A/C, ANY THOUGHTS


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.
