My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
If your model uses an after market alarm that has been installed I have seen in several cases before where the alarm control unit itself is the cause needing replaced to correct this here or the wiring due to the after market system has shorted needing repaired.If you do have an after market system I would have this checked/tested to see if the alarm is the cause and if no after market components are installed let me know.
Thanks Pete

There is no aftermarket alarm, the car is pure stock, and I have checked the fuses

Was anything done on this vehicle that may have caused this fault at all before this issue occurred?
Customer: replied 1 year ago.
Hi Pete, no the car has 114 K miles and is maintained til now at Lexus, I am expecting some electrical suggestions, check switch for continuity or resistance, apply 12 v to this side of switchh , by pass the switch to check out the motor......if this ? then replace this vs just me going ahead and replacing the door lock motor
