AC relief valve blew, what's next?

It's a variable speed, variable pressure system... Amount of refrigerant and lubricant is defined by weight in an expensive machine, not pressure.

Here's a link to the various possible scenarios you're likely experiencing: Oh dear! A/C blowing warm air - where's the cold? | PriusChat

 

In my experience, those valves are one-shot. You replace the valve if it is separately available, or the compressor otherwise.

Then, on the next attempt, make sure the system is well evacuated, then charged with the correct amount of refrigerant by weight.

 

Yeah the valve shot you can't reuse it Don't put any more gas in the system till you work that out I don't know if that's a pinned piece of soft metal in a brass bolt type of affair brass plug type of affair. But it'll need replacing you can swipe on out of another car because usually people don't do this Even when overcharging usually in these cars the electric compressor will lock up well before this valve blows so you had a pretty strong compressor there buddy or?

 

Every time I have seen one of those valves pop off, they never fully seal again. At best they seep just a little bit.
