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!
