1998 Ford Explorer 4.0 V6 with 115,805 miles and no OBDII codes when scanned.
Location: Phoenix, Az with a outside temperature of 95 degrees and 10% humidity.
AC Pressure: The Low is 50psi and the High is 150psi.
Problem:
When the AC is on and the engine is idling, the cabin air vents blows ice cold air. When the accelerator is pressed, while in (P) Park or (D) Drive, the compressor continues to run but the cabin air vents blow warm air. The pressures stay the same at idle and when accelerating.
I have checked all the fuses, and they are good. All fluid levels are where they should be.
Any suggestions for what or where to start trouble shooting would be greatly appreciated.
By "The pressures stay the same at idle and when accelerating" do you mean stays at 150 and 50? Or do the AC pressures equalize? Cause if they read the same then you got a bad compressor. Besides having a low reading on the high side, You may have water in your system, in which case you just need to evac the system for 30 minutes+ and then refill your system to spec.
The low is 50psi and high 150psi at idle and when accelerating. The low and high pressures are never the same and do not equalize.
I will try evacuating the system and starting fresh and see what happens.
Thanks
