yes i have evacuated & recharged the system.the same pressure still.the cooling fans are running also if i put air over the condenser it dont change gauge readings. i believe the expansion valve is stuck in the open position or a bad compressor.i evac the system for 2 hrs.

2005 ford five hundred ac pressures at idle low side 60 psi high side 225 vent temp poor.if you increase engine speed to approx 2800 rpm pressure on low side drops to 35 psi high climbs to 300 psi & vent temp feels good.
