I have 2007 prius.yesterday while driving first the AC stopped working then after some time all of dashboard lights like triangle,engine,ABS,hand brake etc became on with a beep sound.when i came home i plug off the 12 v battery terminals and all the lights were off and car was normal.what could it be?????
Check your inverter water pump, open the reservoir by taking the cap off, then push on/off button twice without touching the brake. If the pump is working you should see water moment and hear the pump on, if not, then the pump is likely dead. Replace the unit, if you haven't replaced the fluid before, now would be a good time to do so.
