1995 F250 AC comes out of the defrost?

the problem is when the baffles move from heat to ac and vent to defrost they either get stuck or the controllerr is bo. this system is built to fail safe in the defrost mode. Thus ac comes from Defrost vents. Apparently it is wide spred with Ford and Chev. As it is in my 2001 Ford F-350, My opinion To much Matel Toy company plastic and cheep parts we pay considerable money for from the dealers. 1) check your controller at the dash probably vacume 2) check the acutator at the butterfly flapper. Some vehicles are easier than others.....

Why does the AC sysmbol light come on when the heat is turned on and set to defrost-vent and will not turn off even when shut off button is hit?

DO NOT FEAR THIS !!! The ac comes on with the defrost: because do you ever use your ac in the winter? me neither. Manufactures have made the ac come on with the defrost to prevent the ac compressor from seizing up. Since we never use them in winter, at least in cold climates. Cheers and drive on.

No, especially since the AC is used when you defrost the windows.

The ac system also removes humidity which helps clear the window faster.


It sounds like your air flow diverter is stuck on defrost. Basically it is a little door that diverts the air fom vent to defrost to feet. It could be either the heater control valve, or te temperature selecter cable is broke.
