Ok heres my problem, Last week I was driving home from work with the ac on and it was blowing ice cold, then all of a sudden it went from cold to hot. my compressor doesnt even kick on when I set it to ac, but heres the wierd part If I turn the heater on and put it all the way on hot it wont change temp, it stay at a nutruel or whatever temp is out side. Anyone have this problem or have any Ideas?

 

What year and trim level is the truck ? ( your profile is blank ).

There is a rash of downloads for the blend door repairs fo the older series trucks. I don't know if these are manual or EATC versions for the bulk of the downlaods.

There could be a few things wrong, like a VAC line not actuating the door, or a problem with the door itself.

Time to start the trouble shooting process, starting with the MY and trim level of the truck.

 

It a 97 f150 4 wheeldrive ext cab

 

TRIM LEVEL ?

 

what is trim level?

 

XL , XLT, Lariat. Indicates if the you have the manual or the EATC HVAC System

 

its a Lariat, but I have found the problem and its working again. now I have to chase down a problem with it shifting, it shifts hard and I already replace the sensor.
