Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to avoid electrical shock (Safety Warning).

2. Inspect Door Switches

Locate the door switches on each door.
Remove the door panel if necessary to access the switch.
Use a multimeter to test the switch continuity; it should show continuity when pressed and none when released.
If a switch is faulty, proceed to replace it.

3. Replace Faulty Door Switches

Disconnect the wiring harness from the faulty switch.
Remove the old switch by unscrewing it from the door or sliding it out of its housing.
Install the new switch by reversing the removal steps and reconnecting the wiring harness.
Ensure the switch is securely mounted.

4. Check Interior Light Switch

Locate the interior light switch, typically found on the ceiling or near the light fixture.
Ensure the switch is set to the "door" position.
If faulty, remove the light assembly and replace the switch.

5. Verify Wiring and Connections

Inspect the wiring harnesses for frayed wires or loose connections, particularly around the door hinges.
Repair or replace any damaged wiring as necessary.

6. Reconnect Battery

Reattach the negative terminal of the battery after repairs are completed.
