Lexus Troubleshooting Questions? Ask a Lexus Expert
Hello and welcome to just answer.I value your input to my questions so I may help you better. You said the motor in the mirror is working with the switch? If that's the case you need to replace the mirror assembly as it is not repairable , no parts available. Most likely the gearing is striped .You can try to move it manually and see if it will grab a thread to operate it but no guarantee. If you want to know how to replace it I can help you to do so, let me know.
Do you need further help or advice?
