Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Tools Required: Basic socket set, multimeter, screwdriver set, and wire connectors.

2. Inspect Door Switches

Locate the door switch for each door (typically found in the door frame).
Remove the door panel if necessary, using a screwdriver to take out screws and clips.
Disconnect the door switch connector and use a multimeter to test for continuity when the switch is pressed.
- Normal Reading: Should show continuity when pressed; no continuity when released.
If the switch is faulty, proceed to replace it.

3. Replace Faulty Door Switch

If a door switch is determined to be faulty, remove it from the doorframe.
Install the new door switch by reversing the removal process.
Reconnect the door switch connector and ensure it clicks into place.

4. Check Wiring and Connectors

Inspect the wiring harness for any frayed or damaged wires.
Repair any damaged wiring with appropriate connectors and heat-shrink tubing.
Ensure all connectors are properly seated and secure.

5. Reassemble and Test

Reattach any door panels removed during inspection.
Reconnect the battery.
Test each door by opening and closing to see if the light turns off correctly.
If the light does not turn off, repeat previous steps to ensure all switches and wiring are functioning properly.
