If this happens while the defrost of ac is turned on, it could be a seized ac compressor which will cause the serpentine belt to squeal and drag making the engine sometimes stall. if it happens with the ac off and the selector on say the floor, or dash vents, the issue could be a bad alternator and battery. this is confirmed when the blower motor engages and the lights dim and then the truck goes dead.

I know it sounds silly, but mine was doing the same exact thing. Easy fix... I changed the oil and added engine cleaner. Evidently, the old oil was gumping up on the sensors, causing them to act up. Immediately resolved the issue.

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

2004 focus 80,000 miles/6 weeks ago, using ac with blower on high, blower gradually shut off and car produced bad smell. Drove home with ac off, blower off, had car checked and nothing found. Now it's...


The 'whirring' sound from the blower motor could be a dry bearing or damaged armature (part of blower motor that the brushes ride on), or just wore brushes. The smell could be the motor winding wires burning due to blower motor bogging down and overheating. You can replace blower motor with new or salvaged one.

Fan problem is the blower resistor module. Very easy to fix ,located right next to the fan under the dash behind the glove box.It has screws that hold it inside the air duct. just remove, unplug from blower motor and replace. A new one costs about 25$.

Blower on my 2004 Chev Colorado only works on high setting #4.


You need a resistor pack, which is likely located in the air box, near the blower motor.
