I have power at the fuse at the PDC
I have power at the fuse behind the glove box
I have checked the relay - good
If the resistor was bad I think I would at least have high speed
Checked the back of the switch for melting etc - Negative for melting
Someone give me something else to check?????
Thanks in advance
I would put money down that its the resistor below the glove box area. On ebay you can get them cheap. Best way to test, find another person who owns a TJ and try it out. If it works, then you got your answer, if not well atleast you know its not that part.
