    Good morning! We have been having issues with our 2013 wipers randomly working. We have installed a new wiper motor and have checked and placed new fuses. Our next check will be the relay, however, we are unable to find any videos, diagrams, or help with how to access it. From one diagram the relay appears to be in the dashboard area, slightly left and below where the display screen is. If anyone has any insights we would appreciate it!!

    If it's working randomly it would seem the relay is working fine because when it randomly comes in the relay is working . Not really a hi current circuit relay to fail usually something pulling hi current thru it failing motor etc . That usually trips fuse

    Somehow you have found information telling you there's a wiper relay in a 2013 Prius. You need to be more selective about the sources you look at. The car's wiring diagram and repair manual can be found like so:

    I think Mendel may have posted an excerpt in this other recent thread (where somebody else also somehow had ended up thinking there's a relay):
