I have a 2005 Chrysler 300 touring with the 3.5L V-6 engine. Car has about 127,000 miles on it now. My problem is the heat and air won't blow. I had a guy check the blower motor and the compressor and he said nothing wrong with either. He thought it to be some type of electrical problem, cause he said when he made a ground wire the unit would blow perfectly fine. My lights also flash on and off, which I consider to be dangerous. I don't want to go back to the dealership because they lie so much. They act as if they don't know whats wrong with the car and I know they are lying. So I hope you guys can give me so basic help. Thanks.
