Troubleshoot interior lights in a Cadillac CTS 2005?

Answer 1

To troubleshoot the interior lights in a 2005 Cadillac CTS, first check the fuse related to the interior lighting system in the fuse box, as a blown fuse can cause the lights to malfunction. Next, ensure that the dimmer switch is set to the appropriate level, as it may be turned down too low. If the lights still don’t work, inspect the door switches to verify they are functioning properly, as faulty switches can prevent the lights from turning on when doors are opened. Finally, if everything else seems fine, consider checking the wiring for any damage or loose connections.
