2000 F150, Heater Problem
Yesterday Morning I got in the truck, started and heater warmed up quickly and all was good. Yesterday afternoon I get in to go to lunch and soon realize the air blowing from the vents isn't warming up! The engine gauges show normal operation....I switch from "Panel" to "Floor" and the same result....cool air even when the temp is full Heat. Strange thing...if I select "Max A/C"....I get warm air ...not hot, but warm.
Does this sound like the Blend Door....or some thing which controls the blend door?
I called the dealership and they said depending on problem...I'm looking at $600 to $700 to fix.
