The air was blowing Saturday and stopped on Sunday. In the past I have replaced the blower motor, the blower motor resister, pig tail and switch. The wires had burnt back. This was done only a couple months ago. Today when I look at the switch the female connector is warped again caused from excessive heat off the switch. What is causing this? I am hoping to get this done before the weekend cold front. My wife will need the jeep to get the kids to school. Thanks for any help.
