Lexus LS Power Window Failure

Hi, I've got a 2019 Lexus LS hybrid with about 135k kilometers. The power windows have suddenly stopped working. No response from any of the switches. I scanned it and it's throwing an error related to the window regulator. Could it be a defective power window switch?

I had a similar issue with my LS (don't recall the year exactly). Window control problems can be tricky. Have you checked the regulator motor itself? The error indicates an electrical fault, which might mean there is an issue with the motor.

Thanks for the quick response! No, I haven't checked the regulator motor directly. Is that a difficult job? I'm not very experienced with car repairs, but I'm happy to get my hands dirty.

Given the error and your lack of experience, I'd advise against diving into the regulator motor itself. It's more complex than just swapping a switch. The error clearly states that your power windows can no longer be operated. The symptoms indicate a potential malfunction of the window mechanism. Based on the error code and symptoms, I suggest taking it to a trusted workshop. They'll be able to diagnose it properly.

Thanks for the advice. I took it to a shop, and it turned out to be a faulty window regulator. The bill came to around 200€. Appreciate the help!
