My front blower for my heat/defrost went out on my 2005 Dodge Durango. The back works fine, but the front does not blow air. We located the blower resistor after reading the threads at this site. Upon inspection we found there was a burn spot on one wire and where it plugs into on the resistor. Will we need to replace the whole wire harness or just the resistor? Thank you for any help you can provide. mph62
