Heater problem
1994 Ford F150 6 cyl Two Wheel Drive Automatic 156000 miles

I replaced my heater core in my truck about 2 years ago and the heater worked great. However, just recently when I went to use my heater it would not work. Air will still blow, but the air is cold. The wire is connected to the temperature controller and I can see the "flapper" opening and closing when I move from cold to hot. Any Suggestions? THANK YALL

The blend door could have popped off of its hinge. Very possible. Tkae the door off for the heater core and move the selector, does it move and completely seal off the core?

Let me know what you find.
