I assume you evacuated and pumped down the ac system after each repair to remove the air. The low pressure switch could be faulty and I have seen damaged prongs. The engine fan clutch needs to be working properly to keep high side pressures down during the heat of the day. I have encountered some demons as well and have put the gauges on the outside of the vehicle and set pressures while driving. I hope you get your situation resolved. I hate when you do everything right and still have problems.
this morning at work i hooked the machine up and took out all the freon and did a 4 hour vacuum to make sure there was no moisture in the system, yes i know 4 hours is a really long time but im willing to try anything at this point. After that i refilled again to 1.50 lbs and started it up. the low side was 30-40 going up and down at idle and high side was 190 to 210. now weird part is when the engine was at 2000 rpm the low side dropped to 15 and high side went to 250. compressor never kicked off and never got any colder either. i have electric fans and they came on once the high side got to 300-315 maybe and stayed on from there.
the scanner shows the outside air as 150 degrees but on the dash showed 101, and another weird part was it showed the evap temp at 100 degrees.
Another weird thing is i played around with the scanner and fooled it to think i have a 2012 f150 with a 6.2l and it showed the outside air at 110 which i can believe sitting still in the sun, and the evap core at 44 degrees, which i can believe too since im getting 63 out the vents on high. maybe its my snap on Zeus scanner, maybe not i dont know.
I have a brand new box sitting in the back seat from ford with a new evap core ready to install this weekend.
