anyone had heater fan issues?
I turned on the defrost when the truck warmed up this morning (fan speed 3) and it came out normal for about two seconds then went to low power in its own zone (not defrost) if that makes any sense. I tried different speeds and different zones (feet, face) and nothing changed. After a second or two the fan sounded like behind the CD player (still set to defrost) anyone had this??
