Solution

1. Preparation

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

2. Inspect Overhead Light Switch

Remove the dome light cover using a flathead screwdriver.
Check the switch functionality by toggling it between "on," "off," and "door" settings.
If faulty, replace with a new overhead light switch.

3. Check Door Ajar Switches

Remove the door panel from the affected door using a socket set and trim removal tools.
Locate the door ajar switch; it may be integrated into the latch mechanism.
Manually press the switch to ensure it engages and releases properly.
If defective, replace the door ajar switch.

4. Test the Fuse

Locate the interior light fuse in the fuse box (refer to the owner's manual for specific location).
Remove the fuse and inspect for continuity using a multimeter.
If blown, replace with the same amperage fuse (typically 10A or 15A).

5. Inspect Wiring Harness

Visually inspect the wiring harness leading to the interior lights and door switches for any damage or corrosion.
Repair any damaged wires or connectors as needed.

6. Test Light Delay Timer (if equipped)

Check the vehicle's settings to see if the light delay feature is activated.
Consult the owner's manual for instructions on how to reset or adjust the timer.
