Thank you for the reply. I was able to by pass the relay switches and diovecersd that the fan has gone out on the primary and the a/c fan is heading that way. It was buzzing and when I moved the fan it started to turn slowly at first and then after a time started to pick up speed. I am replacing the fan motors. I also had a question on what would cause the engine to surge after warm up. It is especially noticed when stopped at a stop light. The check engine light does not come on.
