I was adding 134 to my lousy dash air and the pop-off relieved while I was doing that. My gauge never got above the green so I'm guessing the valve needs replacement.

here's a pic of the pop off and location...if any one is having loss of Freon... this is a place to check... alpines run at extreme high head pressure when running stop light to stop light

Watching this post with interest, I have the same symptoms with my AC. Even had dye in system to look for leaks to no avail. When they recharged my system, it was cold for approximately 45 minutes then no more. So now we have just been using the roof top units while traveling.
I own an auto AC shop...one of most over looked ,and most don't know it's there is the pop off valve...found this out with years of street rod ac repairs... they also have cooling issues to the condensor
