AC on my enclave quits. The vent still blows air. When I turn my car off, the engine fan is still going. Once it stops, I can restart my car and the AC works again. Any ideas? Thanks.

On most vehicles that have air conditioning, the A/C engages automatically when the defrost mode is selected to dehumidify the air . Drier air helps clear condensation from the inside of the windshield and front side windows faster. I don’t understand why GM would lock out the A/C… [image] Jenni…

If the engine gets too hot, or the computer thinks the engine is getting too hot, the computer will shut off the AC to prevent the engine from overheating.

Why should a car fail to crank when the owner turns the key to “start”?

It’s not normal. It did not do that when I first bought the car. The AC light button turns off when the AC cuts out. I turn the car off. The engine fan continues to run. When it stops, I crank the car back up and the AC light, and this the AC comes back on.
