Hey guys i purchased a 04 F-150 love everything about it so far. Found out this week that the heat is not working. The Blower fan works just not blowing any hot air. I don't belive it has to do with the thermostat because the temp gauge doesnt very at all. Also dont think its the heater core no coolant smell or foggy windows inside the truck. Could any of you guys point me in the right direction Any help is greatly appreciated thanks!

Welcome to the forum!

It sounds like either the switch that controls the mode door actuator or the actuator itself. The panel mode door actuator can be accessed from underneath the LH side of the instrument panel.
