Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Remove the Hazard Light Switch

Using a trim removal tool, carefully pry off the trim panel surrounding the hazard light switch.
Unscrew any screws holding the switch in place using a Torx screwdriver.
Gently pull the switch out from the dashboard, taking care not to damage the connectors.

3. Inspect and Test the Switch

Visually inspect the switch for any signs of wear or damage.
Use a multimeter to test the switch functionality:
- Set the multimeter to continuity mode.
- Press the hazard button and check for continuity between the terminals.
- If there is no continuity when pressed, replace the switch.

4. Check and Replace the Fuse

Locate the fuse box and identify the fuse related to the hazard lights (refer to the owner's manual for the exact location).
Remove the fuse and inspect it for continuity.
If the fuse is blown, replace it with a fuse of the same amperage rating.

5. Reassemble and Test

Reinstall the hazard light switch by reversing the removal steps.
Reconnect the negative battery terminal.
Test the hazard lights to ensure they function properly and turn off as expected.
