Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect Door Switches

Locate the door switches (usually mounted in the door frame).
Remove the door panel if necessary to access the switches.
Test each switch with a multimeter to ensure proper functionality (should show continuity when pressed).
If a switch is faulty, proceed to the next step; if all switches function correctly, continue to the next section.

Disconnect the wiring harness from the faulty switch.
Remove the switch from its mount (may require a small flathead screwdriver).
Install the new switch by reversing the removal process.
Reconnect the wiring harness securely.

4. Verify Overhead Light Switch

Check the overhead light switch; ensure it is set to the "off" position.
