Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect the Light Switch

Locate the interior light switch, typically found on the overhead console.
Ensure the switch is set to the "door" or "off" position.
If malfunctioning, consider replacing the switch.

Open each door and locate the door jamb switches.
Manually press each switch to see if the lights turn off.
If a switch is stuck or faulty, remove it using a socket set and replace with a new switch.

4. Test the Interior Light Relay

Locate the interior light relay in the fuse box (refer to the owner's manual for location).
Remove the relay and test it with a multimeter for continuity.
If defective, replace the relay with a new one.

Reconnect the negative battery terminal.
Start the vehicle and check if the interior lights function correctly.
