F-150 2002 Heater Blowing 80 degrees
My 2002 150 heater only blows lukewarm air. I've read a lot of posts and troubleshooted everything i can think of: coolant full, thermostat replaced, heater core flushed and hoses both hot, blend door working fine, and replaced switch that controls modes (floor, defrost, panel, etc.). Is it normal for the box around the blend door to be cold when heat is on; I thought that was strange. I'm stumped. Anyone have any ideas?
