    Hmm, sounds the dark blue wire might be damaged between the fuse panel and the splice that goes to the PDC and the heated mirror switch. In any case, there is another "dodge forum" that has a collection of factory service manuals which have wiring diagrams and connector pinouts etc..

    if i could just find that dark blue wire location in that connector pin out i think i would have it...its bad i have to do all this outside... truck is to tall to fit inside the weather is crazy here... i do remember seeing that wire i beleave in that molded wire harness that goes around the dash it was spliced...and i think it went to the blue wire on the heated mirror switch...the light blue wire with a yellow stripe from the heated mirror switch was melted all the way through the harness...

    since i have power on the proper fuse at the fuse box, anything wrong with using a fuse tap to hook that blue wire up? something like this...

    Well you stated above that there is power at the dark blue wire behind the fuse panel so I would just put in a new wire from there to the connector at the firewall. That way you still have the factory fuse. Either cut the wire and put connectors on it or use the wiretap style which might be easier.

    It could very well be the blower motor resistor, the ceramic heats up and crumbles and the various parts break away, pull the resistor and check it, the damage will be obvious, don't buy replacement via autozone mega expensive, check out amazon I just bought one for $13 bucks free shipping.
