So I have this 2003 Exp that appears to be operating within it's specs for AC but is not cooling sufficiently.
High side = 217psi
Low side = 62 psi
Ambient Temp = 100F
Vent temp = 70f
According to Ford's service manual this is within the normal operating ranges. According to SOME online charts this is also acceptable however I've found quite a few common charts that state the high side should be more in the 340 psi range.
If the 340 psi value is correct it would seem the compressor is a little weak perhaps?
What do you all think?
P.S. The system is currently charged to factory spec of 54 oz for a front and back AC system. I made sure it was charged to spec prior to further diagnosing.
