Q: Air conditioner blowing hot air. Then fan was running low then sped up to high.

asked by on October 13, 2016

Hi there. This morning while driving to work, the air conditioner in my car was blowing hot air. Then as I neared work the fan suddenly dropped in speed then immediately sped up again. On my way home it was still blowing hot air. I left to go to auto zone, (who were no help at all) and while I was parked there after getting gas and turning off the car, all of a sudden the air started blowing cool; not cold, but cool. Of course. It's been doing this off and on very sporadically lately. I live in AZ and it is still in the high 90's. I appreciate any help you can give me. Thanks in advance.

My car has 79000 miles.
My car has an automatic transmission.
