I have 2007 v6 with 46547 miles. It just started acting up in the last 2weeks. When I accelerate slightly or aggressively it shuts the blower motor off or seems to. As soon as I lift out of the throttle blower motor blows again. It has never done this before in the 5 years I have owned it. I have heared about computers that shut a/c off for power reasons. I don't believe this is what is happening with mine. Is the a/c & heater system controlled by vacuum or electrically with actuators . What is my fix???
