While idling and the a/c turned on, there is a loud relief of refrigerant/ gas. When it first happened I thought it was coolant and maybe one of my soft lines for the heat exchanger blew out but that's not it. and I've seen no loss of coolant. Hard to tell where exactly its coming from, on top of the compressor, and I'm not sticking my face up there when it's running lol. This happened once the other day when I was taking my son to school and had the car idling in the driveway. The ac stopped working after that, so I recharged it thinking it was just low since it hasn't been serviced since I bought the car. Rechecked it, ac blew cold and no issues. Started the car today 85 degree day and had the blowout situation again. I'm leaning towards the relief valve, o rings, or the compressor itself.
Just wondering if anyone else had this issue before I rip into it. Thanks

Get yourself a UV light and check all of your lines, the leak will be glowing. I have found a bad oring 3 times now like that.

Yea I think I'm going to inject some dye into it. It should be pretty evident when I look up I there with a inspection minor, its pretty scary sounding when it blows out lol.

When you turn on the A/C make sure the coolant fan comes on, if it doesn't the A/C compressor pressures will skyrocket causing the pressure relief valve to blow off the excess pressure.

There should already be dye in it.
Most cars if they have had the ac serviced do but not all shops put dye in unless they're trying to find a problem. Most dealers don't.

Yea not that you say that when this happened that second time after charging it, i don't remember hearing the fans kick on, I think I was focused on the loud bursts of gas lol

Been a minute since I've been back on the actual website, just been popping on the Facebook page mostly. But looking story short got the a/c working again of course right after the heat wave lol. The fan/pressure switch on the ac discharge line failed. So what must have happened is the compressor kicked on, fans wouldn't run, pressure spiked and lifted the relief valve. So after replacing the switch and recharging the system I've had no issues. Thanks for the help fellas. Hopefully this will help someone else who runs into this problem.
