Re: Heater fan plug melting
That plug goes to the resistor assembly inside the ventilation plenum. The resistor is what gives you low and medium on the fan speed. The high speed should run straight from the fan relay. Looks like someone has incorrectly wired something.

Re: Heater fan plug melting
Talked to the shop and theyclaim it was just plug n play on their end. Any ideas why the connection is getting so hot? It appears I only had one speed which was high if that has anything to do with it.
