[QUOTE=BLT gmc;7068558]BB72CHEVKT-Over what peroid of time did your wiring melt? And how old is the wiring? I just want to make sure I have read post #1 accurately. Bruce[/QUOT

All new wiring, connectors/plugs, and new heater/ fan control. It was almost exactly 90 days. It was apparently melting a little each day. I thought the smell was from the new heater core but it was apparently the power wire going to the fan controller. I have ordered a new wire and resistor.
