Problem Description and Possible Solution
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.

my a/c blower does not go off even when my key is out of the ignition. the temperature gauge goes from 80 degrees all the way down to 10 degrees and back up again intermittently. Now my a/c says it's on full blast but nothing is coming out of the blower at all.
Speeds 1-4 work, #5 quit today, nothing at all. After reading reviews and some internet searches on different sites, I've narrowed the problem down to a faulty resistor and purchased one online through Amazon. I'll let you know if this is successful as with others to remedy the problem.
when i turn on my a/c the engine cuts off an sometimes idle up an down then cut off
front Blower motor stays on with key out of Ignition.
Level 1,2,3,4 on A/c not working
Blower does not work at level 5. Only runs on levels 1 - 4. Replaced blower resistor and that solved the problem.
First blower stopped working on 5. Then gradually the others went out . now no blower at all. Heat or ac
Rear A/C Heater doesn't work
Mine does not blow air out unless it gets a suction. If I roll both windows down and then back up the heat/air will start working. I have also had the fan stick on high and not stop even after shutting the car off. We had to remove the fuse under the hood to get it to stop. I just read this and hope that changing the blower motor resistor under the dash will fix my issue too. If anyone else has had this problem and knows how to fix mine please help. Thanks
started having problems with blower motor not working on 5, the cluster for the dash gages and the fuel cap started causing check engine light to come on all problems seemed to start happening right around the same time
had to replace blower resistor myself
Speed control #5 nor working.
The HVAC fan will only run when it is set to 5.
Heater only worked on speed 4-5. Independent repair shop $55 part, $25 labor.
Bach AC/Heater fan does NOT WORK !!??
My damage all happened when my door shorted out and caught fire in wiring from my blower and air conditioner. Burnt wires up from the blower and on. My front vents do not blow at all. This happened during the same time when my door controls stopped working. And it shorted out my fuel gauge Everything shorted out. And none of it still works all but my door. I took it back on recall....... sure wished GM stood up for there products.
The blower motor went completely out. Had to be replaced.
works fine on all settings, except 5 which is the highest. when I switch it to the highest speed its just like I turned it off.
I had this problem. Blower continued to remain on even after vehicle was shut off. Resistor was replaced but now my heating system for the second and third rows of the vehicle doesn't work. Heat and am to the front of the vehicle only.
only high blower speed had to replace speed resistor
