Need a truck pro for Ford Air Conditioning Systems?
I have a ford F150 extended cab, I checked the AC ssystem and the pressure guage in the suction side states that it is 45 psi. The system contains enough 134A freon and oil for the sytem. I've listened to the compressor clutch kick and out when activated. I've checked all of the fuses and they are fine. If the freon is low the system would not turn on. The question is this: Is the hot/cold selector going out and if so, is it a vacuum dial system or electrical? Single or a complete HVAC component module? I need all ofthe help that I can get. I can figure most of the truck, but the ac systems is something that I am not 100% sure.
Thank you for your time and concern.

Since you are unsure of the workings of your AC system, my only suggestion is to have someone who is look it over. Just because the low side says 45 psi, says nothing about the high side.
Low high side pressure prevents proper cooling.
