    I washed my Prius today at a local car wash. I pressure washed inside the hood. I washed the car around 10am. The car was running for most of the day. It started with the left blinker not working. Then at about 8pm, I went to the store and the car started. Once I came out of the store and tried to start the car, the car would not start and all the lights in the dashboard were lit. Any ideas where to look? Do I let the car completely dry from the inside?

    Checked the LA weather; you’re in luck on that front at least: leave it out in the sun. Have you got compressed air, or a leaf blower? Try to clear residual water as much as possible, as soon as possible. Disconnect and blow out every under-the-hood electrical connector you can manage.

    Verify your 12v first. If it’s good I would certainly blow dry the ecm area next to the fuse box.
