Problem with air conditioner
On several occasions this summer, my air conditioner started blowing warm air. Sometimes this would happen after a short 15 or 20 minute drive, and at other times after an hour or two.It seemed like really hot days were a factor. The car is currently at the dealership, but after talking to the service department, I don't think they will be able to get the car to blow warm air and come up with an answer. There are no leaks in the system and the freon is properly charged. Can anyone tell me what I should be looking for.
