First thought was low freon and perhaps air in system. System was evacuated then recharged. Only get hot air at idle and when driven only cool air for a short time before hot air starts.
The low side is high about 90 and the high side is 150. Possible compressor problems?
Above solution is correct, had the same problem with mine and it was the expansion valve.
Those pressures show me that the metering device is stuck open. meaning orifice tube or expansion vavle, i think this vehicle has the expansion valve. your symptoms describe what is normally the complaint associated with stuck expansion valve also. you should evac again and replace that expansion valve. i'd say 9 times out of 10 those pressures you speak of is stuck valve. but to finish the testing, check the compressor by reving up to 2000 rpms, if the low side pressure drops down a little but(10-15 psi) and high starts to rise, this tells you that compressor is good.

low side way to high sounds like compressor getting weak.When you rev it up with guages hooked up what does pressures do ??
