    Good morning,

    The air conditioning on my 2018 Prius Prime has stopped working.
    I went to the shop to check for gas in the circuit, but it's present and there are no leaks.
    Connecting the diagnostic computer shows error code B14A7, which can't be cleared. It seems to be identifying a faulty valve in the A/C circuit.
    Does anyone have the Toyota program to diagnose this problem? Has this ever happened to anyone?

    Thanks
