- If a switch is faulty, replace it with a new one.

3. Check Wiring

Inspect the wiring harnesses connected to each door for damage or corrosion.
Repair or replace any damaged wiring.
- Use electrical tape or heat shrink tubing to secure any repairs properly.

4. Test Interior Light Switch

Locate the interior light switch, typically found on the overhead console.
Remove the switch and test it for continuity using a multimeter.
- If faulty, replace the switch with a new unit.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Test the interior lights by closing all doors and checking for proper operation.
