I would say that with 2 lbs of Freon in the system that the high pressure switch is stopping the compressor from working and being destroyed from liquid on top of the pistons. An ac system works by compressing gas to liquid and then releasing that liquid through a small orifice into a vacuum created by the ac compressor .With excessive liquid then that turning to gas situation will not occur and liquid will get to the pistons and stop the piston movement. I recommend that you take it to a ac specialist and have the system pumped down into a receiver tank and then the correct amount of refrigerant gas added .
SOURCE: A/C REPAIR AND IDLE PROBLEM
Clean the trottle body and air bypass valve, then disconnect the battery for 5 minutes, this should cure your concern.
SOURCE: Recharging A/C freon
with the engine OFF you can charge it through the high side freon must be accurate among
SOURCE: hot air comes from my ac
I had the same trouble; it turned out to be a broken cable that controls the air temp. Look under the dash by the clutch pedal. Hope this helps.
