What is the sign of door sensor close kaput. If it s not working do you think interior light is not responding to on/off and alarm will be triggered if i lock using remote? In my case the interior light is working as per normal and no alarm triggered.Display on instrument cluster also did not indicate right door open. Maybe it works differnetly. I understand to remove and fix the actuator is rather PITA. I hope I don't have to do that.
Appreciate your advise.
since you have open the door and work on it, check for loose connection or something blocking the actuator.
high possibility is the actuator that is the culprit.
based on error 83 , it look like that the door close sensor is not functioning. check that out first.
will try to extract some info on the wiring from the WDS later.
