So drove my vehicle to work today, AC Worked fine, same out no AC. Had someone check the pressure its over 120. When we release some of the pressure only AIR came out but when we stopped top check again pressure would raise again. AC Compressor does not turn on which I was told is normal because of the high pressure on the low side. Was told could be the orfice tube? Any ideas?

I suggest you take it to an AC shop and have them further check it-all this I was told is not gonna make it-pressures being too high could mean its overcharged or air in the system. High on the low side also could mean a compressor problem

I know there was air on the low-side they were saying could be orfice tube, does that sound like a possibility. I don't want to throw parts and money as its expensive when it comes to the AC.

If its getting cold and then turns warm-could be freezing up due to air and moisture and ice is forming on the orifice-Your best shot is bring it in to the pros-Sorry this is all I got for you-
