'99 F150 AC low and high side pressure readings
Been troubleshooting ac on my Dad's truck. Read the FAQ and after going through all the diagnostics on the ac (low pressure switch, high pressure switch, ac clutch relay, coil resistance all OK) I found issue with clutch gap. I removed the washer in the clutch and put everything back together and the clutch is engaging properly now (gap is around .020 now) and seems to be working ok. I borrowed a set of gauges from a friend and want to verify the low and high side readings to see if the charge is adequate. Getting about 48F air out of the vents with outside temps around 85F. Could someone give me an idea of what the low and high side pressures should be running at that outside temperature?
Thanks for the help and the nice HVAC FAQs.
