Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and a wiring diagram for the vehicle.
Ensure the vehicle is parked on a level surface with the parking brake engaged.

2. Inspect the Ignition Switch

Locate the ignition switch (typically near the steering column).
Using a multimeter, test for continuity when the key is in the "off" position.
If the ignition switch is faulty, replace it using the following sub-steps:
- Disconnect the battery to prevent electrical shorts.
- Remove the steering column cover to access the ignition switch.
- Unplug the electrical connector and remove the mounting screws to replace the switch.

3. Check Dashboard Light Dimmer Switch

Locate the dashboard light dimmer switch, usually on the dashboard or near the headlight switch.
Rotate the dimmer switch to see if it affects the dashboard lights.
If the switch is faulty, remove it and replace it:
- Disconnect the battery.
- Remove the switch by unscrewing it from the dashboard.
- Install the new dimmer switch and reconnect the battery.

4. Inspect Wiring and Connections

Visually inspect the wiring harnesses related to the dashboard lights.
Look for frayed wires, loose connections, or signs of corrosion.
Repair any damaged wiring or connectors as needed.

5. Check for Aftermarket Devices

Inspect for any non-factory installations (e.g., alarms, radios) that may interfere with the electrical system.
Disconnect any suspect devices and test if the dashboard lights turn off.
