Hey guys, my a/c compressor is disengaging too often and when i took off the plastic caps to attach the gauges, the high pressure port started to shoot off alot of air or freon. Should this happen when just removing the cap or is the port bad? It was also covered in black oil.
I added 24oz of 134 and the gauges read 50 and 215psi. The air blew cold for a while but then blew hot for about 5 minutes. How can i tell if im low on freon?
Thanks
Feel the inlet and outlet at the evaporator if its an accumulator type system with engine running and A/C on ( where the tubing goes in from a tall usually black or silver canister at the firewall near the blower motor). Both should be cold and about the same temperature.
The suction line from there all the way to the compressor should be cool too if it has a full charge.
The other line ( discharge) will be hot.

If it gets cold once, you have enough-- unless it is leaking out as fast as you put it in. Does the compressor still engage when it is blowing hot?
