    The blower for the back of the vehicle is stuck on and is blowing hot air. It will not turn off and it won't blow cold air. Also, The blower level 5 in the front part stopped working. The air conditioning is not working in the front either.

    Blower motor ran constantly then stopped all together. Seen recall for this on other GMC models but not this GMC Denali Envoy, WHY?

    Fan blower stopped blowing. I removed the blower and checked the voltage. It showed 10 volts on level 1, 2, 3, and 4, and 12 on 5. Thought that since I was getting voltage and it changed at level 5 that this was enough voltage, so I assumed that the blower motor went bad. Nope, after spending $100 for a new blower motor, plugged the new one in and still nothing. Usually the moving part - the blower motor - goes bad not the simple relay. I have never had a blower relay go bad. Frustrating. I guess the next thing is to figure out how to replace the relay.
