RC power window failure
Summary of the thread
The 2023 Lexus RC hybrid experienced a complete window regulator failure, with neither window responding and a diagnostic scan showing an error. The issue was suspected to be a faulty power window switch. After checking the fuses and finding no clicking sound from the door, it was confirmed by a Lexus workshop that the power window switch was defective, leading to its replacement.

Thanks! Fuses look good. I don't hear any clicking. Does that point to a specific fault in the window mechanism or the switch?

Okay, if the fuses are good and no clicking, it's likely the switch or the motor. I'd get it checked by a qualified technician to avoid issues dismantling the door and window, especially with the electronics.

You were right. The Lexus workshop agreed: defective power window switch. Repair, including door panel removal and switch replacement, was 200€. Thanks for helping me avoid a potentially long and expensive job!

Interesting, I have an RC as well with the same symptoms. Have you checked the power window fuses? When you use the switch, can you hear clicking from inside the door?
