The blower stopped working on my 2003 Dodge Durango, when I pulled the fan resistor I noticed one of the wires had insulation that had melted. I moved the wire and got the blower working but noticed the tempature of the wire started to climb. I have a new resistor and can replace it the question is what do I look at as the source of the wire overheating, I figured either the resistor or the fan control head. Any other ideals out there.

Thanks

The resistor by name and design is made to produce heat. Is the insulation on the connector? If so, that is just about a normal occurance for the resistor going bad. It will produce a lot of heat and cause coating to melt. I would change the resistor and not be overly concerned if all the fan speeds work properly. If there is a different sound to the blower then look at the current draw to the blower. You probably will be OK with just replacing the resistor block.
