Yesterday I heard a quick and strange noise after pressing the AC button while cruising.
When I got home and opened the hood, I noticed the back of compressor and hood underside was coated with refrigerant. Then out of curiosity I turned on the AC again and it was ice cold and ran fine.
Now, I normally turn on the AC while idling, but in this incident I did something different which was turning it on while cruising (~2,000 rpm or so).
So my guess is the high-side pressure had probably spiked when the compressor was engaged at a higher rpm, therefore causing the pressure relief valve to activate.
Has something like this happened to you guys?
BTW, I hook up the AC gauges and while idling I'm reading 35 psi low-side and 200 psi high-side at 85F ambient temp, so those numbers are within spec.
