Note. To perform work on replacing the interior light switch, the battery can not be disconnected, since when the switch wire is closed to «mass» only the interior light will come on.
Removing
1. Using a Phillips screwdriver, unscrew the screw securing the switch to the door pillar.
2. Remove the interior light switch from the hole in the door pillar and disconnect the wire tip from the switch output.
The limit switch located in the door pillar often stops closing the circuit to «mass» due to corrosion occurring between the self-tapping screw of the switch and the walls of the hole into which the self-tapping screw is screwed.
Replace the failed interior light switch.
Installation
Install the switch on the car in reverse order.
