Took care of a nagging electrical problem with the passenger door-open switch for the interior and door clearance lamps.
In the past few months the switch seldom closed the circuit when the door opened. I could always get it to go by wiggling the switch plunger after the door opened.
Removed the switch, found there was a contact pad in it, then took a dressing file to it to renew the surface of the switch contact and re-mounted the switch.
