Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.
You probably have a bad temp sensor. You have 4 temp sensors in the vents, one for the cabin temp, and another one for outside temp.
If one is not reading correctly, you will have hvac performance problems. This should be under warranty.
The ac compressor will not even run if the outside temp is below 65 degrees.
Yes a faulty sensor will prevent the compressor from coming on. The only way to check the sensors is with the GM tech 2 scan tool.
