Mirai Power Windows Failure
Summary of the thread
A 2020 Toyota Mirai experienced a complete failure of its power windows, with no dashboard warnings but an error stored in the system. The issue was suspected to be either a simple fuse problem or a faulty power window switch. After further investigation and a visit to a mechanic, the problem was identified as a defective power window switch, which was then replaced.

I haven't checked the switch, how would I even do that? The car has 155587 km. Is it possible that the regulator motor is broken?

At that mileage, a faulty window regulator or a defective power window switch is plausible. The error code points more towards the switch, but honestly, diagnosing it properly requires tools and know-how. Maybe it's time to visit a workshop?

Thanks for the advice! Took it to a local mechanic, and you were right – it was the power window switch. Cost me about 200€ to replace. Appreciate the help!

Could be a fuse, but the error memory suggests something more. Have you checked the power window switch itself? Sometimes they go bad. Also, how many kilometers are on the car?
