    first post so I apologize if the wrong format or wrong thread, I am just desperately seeking some insight about my car. It’s a 2006 Prius, so a few years old, but new to me as I just bought it privately a month ago, and it’s my first Prius so I am totally in the dark here.

    I was driving yesterday, stuck in a little traffic so going between 15-20mph, sort of stop and go. Without warning my radio shut off, I looked at the display screen and it was black, looked at the instrument panel and it was black, tried to accelerate and nothing happened, the car was OFF. The wheel didn’t lock up, and neither did the brakes or gas pedal.

    I coasted it to the side of the road, and tried the hazards, which worked. The headlights, interior lights, and even lights on the instrument panel seem to be working. If I have the door open, the red symbol lights up, if I lock it with the key fob it beeps and the indicator on the dash shows, and the automatic locks work too. But the area where the mph shows and the display screen are completely black, and I do not have the READY light. The car obviously will not start either.

    Before this total shutdown I had no warning lights on the dash, was current on maintenance and had experienced ZERO mechanical or electrical issues with the car. I already checked the airflow to make sure there wasn’t a blockage, and the engine coolant reservoir is full. Does anyone have any ideas what else I can check before I have to shell out to tow this thing to a Toyota dealer? Thanks!

    Check the AM2 fuse. If it blew, the inverter coolant pump motor shorted out.

    Sure enough it was blown! Great tip, thank you so much!! On my way to buy a replacement, but will it just blow again? Does the inverter short cause the fuse to blow, or does the fuse blow and short the inverter? I’m just trying to get to the origin so I can fix it for good. Thanks again!

    If you disconnect the inverter coolant pump wiring harness connector you can replace the AM2 fuse and drive a short distance without causing damage. The distance depends upon ambient air temp.
