Ford ExpeditionTrue expeditions require additional transportation conveyances: horses, boats, cars, for example. With a towing capacity around 9,000 pounds, the Ford Expedition can tow any of these. Ford adds a new top end King Ranch model for 2008, as well as an available rear backup camera and power-retractable running boards. The Expedition is meant for utility, not posing.

I'm not a professional mechanic, take my suggestions with a grain of salt, or a cup of coffee
At the bottom of each post there is a little icon
Clicking it gives feedback to the moderators, and poster regarding which posts are most helpful.
You could also try flushing out just the heater core. Of course, on my wifes '99 Expedition I chose to cut the heater hoses and install a copper pipe with hose clamps afterwards, instead of trying to disconnect the factory heater hoses at each end.
Be sure and use only low pressure waterhose water & flush the heater core out BOTH ways!! If this doesn't work, then a failing blend door actuator or a broken blend door shaft is at fault.
Good luck & keep us posted.
