A/C pressure release valve?
2016 Lariat 5.0
I've noticed that randomly some times when I start the truck and turn on the A/C I'll get what sounds like a pressure release or a blow off valve for about half a second. Doesn't seem to happen every single time, but maybe once in a 1-2 week period (that I've noticed). Truck runs fine, A/C works fine, but it's unusual to me the there's a quick blow off right after turning on the A/C. Normal? If not, any ideas what could be wrong/broken?
