After driving the truck today my air now blows warm, havent had a chance to throw the gauges on yet to see if the pressures have changed any but I don't think they would have they were holding steady yesterday
Is the compressor still cycling?
With the pressures your guages are showing it should have sucked that can of freon down in less than a couple of mins with the switch jumped out. Almost sounds like there is a problem with the low side connection or the compressor is shot and not building and suction or pressure. Im leaning towards compressor being shot.
i would rule out the charge before going any farther evac hold it make sure no leaks and charge. with a neg pressure on it should be easy to charge numbers look low to me as well.
