I have a 1999 Expedition Eddie Bauer 5.4 motor and has no heat. It just blows cold air. I replaced the thermostat with a new one, flushed the heater core, both hoses coming from the heater core are hot, I went ahead and took apart the center console to access the blend door actuator. I pulled it out but left it plugged in and I changed the temp from hot to cold back and forth a few times and the blend door turned back and forth which tells me that it’s fine. Coolant level is good and the temperature gauge reads normal. I’m at a complete loss as for what else it could be. Does anyone have any ideas or know something I have clearly missed? Thank you!
