Lexus GX Power Window Failure

I'm experiencing an issue with my 2019 Lexus GX (gasoline engine). The power windows are completely inoperable. I've scanned the system and found an error stored in the error memory related to the window regulator. Given the symptoms and error code, I suspect a defective power window switch. Has anyone else encountered something similar?

I own a Lexus GX as well. I recall facing a very similar situation with my power windows. If I am not wrong, I remember that my mechanic mentioned it has something to do with the car window mechanism. Does the error code specify which window regulator is failing?

Thanks for the swift reply. No, the error code doesn't specify a particular window. All power windows are affected simultaneously. Was that also the case for you?

Yes, that mirrors my experience precisely. Since all windows are impacted, it strongly suggests a central component like the switch or a shared wiring harness. However, without further diagnostics, pinpointing the exact cause is difficult. I would advise consulting a qualified automotive repair workshop for a proper diagnosis and repair of the car window. I hope this helps!

Understood. I appreciate the confirmation; it validates my initial assessment. Based on your feedback and the troubleshooting I've already performed, I'll proceed with replacing the power window switch. Parts and labor are estimated around 200€. Thank you for your input.
