Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.

Tools Required:

Multimeter
Socket set
Screwdrivers (flathead and Phillips)
Wire brush or electrical cleaner

2. Inspect Door Switches

Locate the door switches, typically found in the door frame.
Remove any necessary panels or covers to access the switches.
Disconnect the wiring harness from each switch.
Use a multimeter to check for continuity when the switch is activated (pressed).
- Expected result: Continuity should be present when the switch is pressed; otherwise, replace the switch.

3. Check Interior Light Control

Locate the interior light control switch, usually on the overhead console.
Ensure it's set to the appropriate position (e.g., "Door" mode).
If faulty, replace the switch by removing mounting screws and disconnecting the wiring harness.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness and connectors leading to the door switches and interior lights.
Clean any corrosion or dirt from connectors using electrical cleaner or a wire brush.
Repair or replace any damaged wires or connectors as needed.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Test the operation of the interior lights by opening and closing each door to ensure they function correctly.
