Disconnect the battery again to ensure safety.
Remove the module by unscrewing or unclipping it, depending on the design.
Inspect for any signs of damage, corrosion, or burnt connections.
If faulty, replace it with a new module, ensuring all connectors are secure.
Reconnect the battery and test the interior lights.
