Ok guys help me out. I have just about spent all my money on this car and still have not got it completely fixed. I have replaced every thing with the heat and air. New complete ford oem duct work, new actuator motors, new vacume motors, new hot/cold actuator and now it still does not switch from hot to cold. The mechanic said it was the control unit (as in the thing with the buttons,I don't know its actuall name
) because he can bypass it and manually make the motor turn it from hot to cold. He has it set on hot rot now since winter is coming pretty quick. How can I test this thing to make sure it is indeed the problem? I took it out and sent it off to be rebuilt and it didn't help. Then the company that repaired it said that they only fix the part that changes from vent to defrost etc... So there is money down the drain. Can it be some thing stupid that I have done like plug the connecters in the wrong spot? Any and all help would be greatly appreciated!! Thanks.
