    try unplugging your blower motor resistor to start with and see if that helps. iv seen this only one other time on a dodge b4

    Thanks for your response.This is what I thought it may be and previously asked a question as to the exact location of the blower motor resistor but did not get a helpful response. I will try that and see if it corrects the problem.Thanks again for your reply.
