Kia Sorento dome light not activating when door opens on Kia Sorento

Some KIA Sorento owners report experiencing issues with the dome light not activating when any of the four doors are opened. This can occur if the dome lamp switch is not set to the "Door" position, which is necessary for the light to function correctly. Additionally, a button next to the dome lights must be properly configured to ensure the interior lights turn on with the doors. If the door ajar indicator lights up, it suggests the door switches are working, but further diagnostics may be needed, such as testing the diode and overhead switch. Owners may also check for voltage changes at the Red/Black wire to identify potential bad contacts in the switch. In some cases, the Electronic Time and Alarm Control System (ETACS) may be at fault if it fails to signal the switch that a door is open. For vehicles with lower-end trim levels, ensuring the rear switch is correctly set is also crucial for proper lamp operation. By addressing these factors, owners can likely resolve the dome light issue.
