This was a good truck when we bought it about a year and a half ago, then the thermostat went out, had that replaced but still no heat, so I put another thermostat in it and still didn't fix heat, no smell of antifreeze so don't think its the heater core, just blows cold air! Not good in the winter time with 4 kids!

took a long time to get warm and worked fine until about a week later and it would not get hot, nothing but cold air . Replaced the heater core this summer because it was leaking, and did it myself saved $ 850.00. this time i changed the thermostat and flushed the rad. but only luke warm air seems like the water is not traveling like it should, so i think the head gasket is blown have to take it to the shop cause i am tired of fooling with iot

The heat only works when its at a high idle or on the expressway. when idling the temperature gage drops and no heat comes out just cold air. The thermostat was changed radiator flushed. Can not figure out whats wrong. We have had nothing but problems with this truck....

I have a 2000 Ford Expedition Eddie Bauer I am getting no heat at all front or back cleaned out heater core changed water pump and thermostat had system flushed don't know what to do next
