2015 Silverado High Country 1500 6.2
Problem 1: Last month my ace was just blowing warm air, not cold. Had my broinlaw helped recharged it with a 18 oz can. Gauge was showing LOW. After refilled, cold air came back normally.
Problem 2: Just today, the AC is blowing warm air again, I did look at the compressor and it is spinning with engine and ac on, which means theres still freons in the system. I also bought new can to recharge just to see if the gauge reads LOW, but when I pressed the trigger... it was showing RED (indicating something other than low or filled). I checked the AC radiator and like some youtubers said, there was a little spot on the side showing possibly leakage. But I don't understand why the gauge would still show that there is still pressure?
Question is why isnt' it blowing cold air while it is still freon in the system? Or could it be other major issues?
Thanks in advance!!
