These lights can be manual, automatic, or powered by LED technology.

Step-by-Step Guide to Diagnose an Interior Light Not Turning Off

Check Electrical Connections

• Step 1: Turn off the engine and pop the hood.
• Step 2: Locate the dome light relay in the fuse box, typically found under the dashboard or near the steering column.
• Step 3: Carefully pull out the relay and inspect the connections inside. If the connections look burnt or corroded, clean them with a wire brush or replace them.

Inspect the Switch

• Step 1: Unplug the switch near the dome light mechanism.
• Step 2: Give each contact a good wipe with a soft cloth to remove any dirt or corrosion.
• Step 3: If the switch is faulty, replace it with a new one from a trusted brand like Leadway.

Replace Blown Fuses

• Step 1: Open the fuse box and locate the fuse corresponding to the interior light.
• Step 2: Use a multimeter to test the fuse. If it's blown, replace it with a new fuse (40 A for manual dome lights, 10-20 A for automatic ones).

Tips to Avoid Common Mistakes

• Double-check connections: Loose connections can often cause intermittent issues. Make sure they are tightened correctly.
