Ac works, High pressure switch good all new compressor/dryer, system isn't plugged in any way, AC is charged front, and rear AC work fine. After about 30 minutes of driving AC light flashes and system quits working. Compressor quits working (fans stay on). I was wondering if its the circuit board that controls the AC?

Really need to scan the A/C computer to see what codes are in there, it could be one of several sensors that has become defective. A parts store scan ala Auto Zone will not be sufficient, you need a Pro level tool with a Pro level Tech to correctly interpret the data. here are some shops: https://repairpal.com/directory?address=92347&car_brand_names=Toyota
