I have a F-150 King Ranch with a heater problem,there is no heat, the blower works, the tempture indicator works, the eng indicate normal. Is there a relay I can't see this as being a fuse problem

 

if your concern is no tempature change, you most likely have a bad blend door motor this has been a problem for a lot of f150's the blend door motor is mounted behind the radio on top of the heater box, sounds easy, but the screws are not easily accessed also u must line the motor up with the door,the key must be in the off postion...

 

Thanks for the info I check it out. Today it was working ok I hope it not going to be one of those that works when it feel like it

 

Im new to the sight and heres my problem . It was 11 degrees this morning and go to turn the heater on luke warm? . Fans fine, themostat shows engine fine! ? Fluids good! Whats up is it my thermostat ?

 

it will work intermittantly still would check it out..

 

You answered your own question pertaining to the thermostat...if the engine temp gauge is showing a normal temp, then the thermostat is working.

Blend door or auto climate box (if equipped). You did not tell us your model; the crystal ball is in the shop right now.

 

thanks senior ford tech will do!!

Lariats have the "auto climate" feature, another troublesome unit. If it is found to be bad, it's unrepairable and on the pricy side to replace.

Hopefully for you it will be something simple; otherwise be prepared for a large repair (and parts) bill from the "senior Ford tech".
