Loss of One or More HVAC Blower Motor Speeds on GMC Envoy

The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

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.

Goes on and off at random.. 5 hasn't worked,in a long time ... every once in a while it works. How do I get this fixed? And how much should it cost?
Electrical things are going out. 1 day it was my seat adjuster, now the a/c

Ac only working when the weather temp Is below 80 degrees. Blowing hot air.

Speed 1 became working only intermittantly for a few month while 2-5 was unaffected, and completely stopped after that. Over the course of 2 years,each speed has now completed this process respectivly. Speed 5 is the only one working at 150,000 miles. Has not been fixed as of yet, doing research now to complete diagnosis before repair is made.

Replace the air conditioner blower. Now I need another one.Don't blow on the number 3 or 4 but, 5 speed is very strong.

not fixed yet. it started with one speed going. I could live with 1,2,3 & 5 no big deal. Then 1,2 & 3 went. I don't like heat or a/c going full blast to keep it cool or warm because it then becomes a nuisance. Looking for recommendations.

My air conditioning fan has made noise since I bought it and just stopped working. This vehicle is a piece of crap. I've had it back at the dealership at least 10 times in 10 months. I'll never buy another GMC.
