LFA Power Window Failure

I'm writing about a power window issue with my 2010 Lexus LFA, gasoline engine. The windows are completely unresponsive. I checked the error memory and there's an error related to the window control system. I've checked the fuses and they're fine. The car has 195667 km. Any ideas?

Have you checked the voltage at the window regulator motor when trying the switch? That'll help see if the problem is the switch or further down the line.

I haven't tested the voltage at the window regulator motor yet. Can you explain how to do that? Where are the test points, and what voltage should I see normally?

Since you're not familiar with electrical testing, I'd suggest taking it to a qualified tech. Window regulators can be tricky to troubleshoot without the right equipment and experience.

Thanks, I took it to a shop like you said. It was the power window switch, just like I thought. The repair was 200€.
