My cavalier recently stopped blowing warm air out of the heater vents. I had the heater core replaced some time ago when it leaked inside my car. After that it seemed to work fine. Now it is not heating. I've had the hoses checked on the heater core and switched them to see it it was the problem. My car seems to blow out a little warm air untill it hits 45mph. Then cold. A local auto mechanic says it could be a cracked head or blown head gasket. There are no leaks anywhere, and there is no antifreeze in the oil. Do you think it is the head gasket or cracked head? Thanks for your response and I appreciate your time.
have the same problem?
