My blower motor works only when you slam the front passenger door. I replaced the ressistor and that didnt help. has anyone had this problem in the past and can help? Can it be a loose wire or maybe a bad motor. Any help would be great. I am going to go outside and hit the blower motor with a sledge hammer and see if that helps. Just kidding..... I will go tapp it with something.... thanks for the help in advance......
