Ford 2000 Expedition no heat

Asked by Jan 31, 2017 at 01:55 PM about the 2000 Ford Expedition Eddie Bauer 4WD

Question type: Maintenance & Repair


2000 ford expedition 5.4L, no heat front or rear. AC works good. Flushed cooling system October 2016 at 105K miles. Soon after the flush no heat--heat for 15-30 seconds then cool air.  Replace thermostat but still no heat. Repair shop said could be blend door. I started the Dorman fix but in the process discovered that the actuator and the blend door are working.   Nevertheless, cut through the glove box and heater box and can see that the blend door is working. Can feel the heater core through the cut out. Heater core gets warm to the touch but not to hot to touch. AC works good, but when switch to heat only get some heat for 15-30 seconds. When I feel inside the heater box it seems to me that the AC never turns off ie... always blowing cool air. What should I do next? Is there a temp control sensor that is not working to turn the cool air/ac off? Should I reverse flush the heater core? Thx"

Purge the air out of the cooling system.

Thx--Purging the air from cooling system helped a little bit. Getting some more heat now (longer than 30 seconds) but not very warm/hot. In addition to the above video being helpful this video was also helpful as I don't have a radiator cap.--https://www.youtube.comwatch?v=Ffnhht1SjWQ Keep adding some coolant to the reservoir to maintain the level. What should I do next? Flush heater core? Keep purging air? Still no heat in the rear/rear heater core but rear AC works good.

U must have radiator cap because the system needs to be pressurized. It will pressurize itself once u start the engine and let it run a little bit. Bleed air from system by squeezing upper and lower hoses then opening the cap just a little bit until water and/or air come out until just coolant comes out being careful not to take cap all the way off. If u still don't get a hot heating core( hot air blowing) change the heater control valve( located under hood in engine compartment 3/4 inch hose running to heating core with the heater control valve in the line. Good Luck!
