Question about 1999 Ford Expedition
I have a Ford Expedition 2003 SUV and the heater stopped working on it. It works once in a while but now it seems to not work at all. What could be the problem and how could it be fixed. A/C works perfect but doesn't throw out any heat when I change the knob to red. Please help me!
This is all to common an issue in many Fords starting in the mid 90's, reason they went to a electric motor to control the air blend door , this motor moves the door air that diverts heat or cold from the AC, or mixes or blends it,the motor has failed or the door is stuck in the air duct, the bottom line is that to fix either problem the dash must be removed, no a job for the home mech, takes about 10-15 hrs to complete.

My '99 expedition heater quit working. The blend door is fine. I suspected that the heater core was clogged. I changed the heater core (what a pain in the ___) !!!! This did not fix the problem. Turns out the impeller on the water pump was completely rusted away. I guess that the only reason the truck would not overheat was because it's so cold outside. (No thanks to GLOBAL WARMING).
