I replaced the resistor and nothing changed. I noticed the wires inside the harness were melted a little and i beleive the wires/switch may be bad. Is this difficult to replace and if so can anyone tell me where to get the parts.

 

u can get the parts right from dodge they will be a lil pricey but ull get it in real quick.

 

that harness at the dealer is 70-80 bucks i had to get one too a while back. and no its not that difficult to fix. heat shrink butt connectors and you will be all set. maybe 20 mins.
