Make: ford
Model: escort
Engine Size: 4
Refrigerant Type: 134a
Ambient Temp: 88
Pressure Low: 35
Pressure High: 365
Country of Origin: United States

88 degrees outside and my escort reads 35 psig low and 365 psig high. line going back to compressor is cold. Last summer the ac blasted in this little car, better then my Ridgeline. I tried adding and taking it some freon but little change. You think I might have an issue with my vent flap?
Advice please.

Is cooling fan (radiator/condenser) working?

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Actually right now, my rad fan is not going on. I am looking into the Constant Control Relay Module because my compressor isn't even going on now.

Actually the cooling fan goes on after the engine gets warm. About 10 minutes.

What was in the refrigerant that you tried to put in? Lubricant? Sealant? Dye? R134a?
