'99 Ford F150 Heater Problem
 

As we approch winter I checked out my heater to find it does not work!!!!!!!!!!! :-hair

I drove my truck into town and open the hood to check the two heater hoses. Both hoses were hot so I can rule out heater core being blocked. :)

When I arrived home, I turned off my engine and listen next to the vent box to listen for the door flap to open and close when I would rotate cold to hot on my temp switch. That too works! :)


:-huh The only thing I do not understand is why my AC Compressor is still running after I rotate the switch to HOT and go to defrost yet no heat only cold air from the AC (again with the temp control to full heat RED).

Now since I am confused .. I am wondering if the temp control switch is bad? Seems after you pass the mid point from cold to hot the switch would deselect the ac compressor from starting. :confused:

Anyone have this problem or going through the same pains?? .. Oh! will will be painfull come winter ... Nebraska areas are sometimes -4 + with high winds. I do not foresee me being in my truck if it doesnt have any heat .... LOL!
