My ac blows cold air. The problem is I never know when. When it blows cold air it’ll blow 30 degree air. When it doesn’t it blows 50 degree air. Compressor, condenser, and evaporator have all been changed as well as numerous sensors. Something keeps telling me me it’s electronic- a sensor or loose wire or a bad connection or could it be something else I’m overlooking? Somebody… Please help!

 

if its getting down to 30* that is not good, the evaporator core is freezing over. Ideal temps are in the low 40s

 

Evaporator and evap temperature sensor have both been changed. Same issue. Cabin air filter is new. Outside temperature sensor is new. My gut is saying the controls on the dash could be it. It used to be a simple vacuum switch. Not now. Lol

 

Welcome

 

Get it diagnosed vs firing the parts cannon at it

I was told today that Ford uses a type of controller either in the rear doors or somewhere in the back of the front seats that sometimes get stuck and will affect the system. Any truth to that?

 

..i have never heard of such a thing
