Computer or ignition switch?
I have a 2003 f150xlt and My power windows/locks, radio (but not radio lights), wipers, and cruise control have all quit. also, the heater valve is stuck in the heat position
All these things stopped at the same time. so i am positive they are related. Went to the ford place and they instantly say the computer is bad, and want $100 to test their claim, but the engine runs great, no codes, and no other issues. Please help. i have taken the drivers window off the tracks just to survive my daily comute. i have had someone suggest the ignition switch may be bad and also is there a way to manually disengage the heater valve?
