Repair the Lamp Ground Connection

Tools Needed: Wire brush, sandpaper, dielectric grease, socket wrench.

Steps:

1. Disconnect the negative battery terminal for safety.
2. Locate the lamp assembly ground wire, typically bolted to the vehicle chassis near the light housing.
3. Remove the mounting bolt using a socket wrench.
4. Clean the contact point on the chassis and the ring terminal of the ground wire using a wire brush or sandpaper until bare metal is visible.
5. Apply a thin layer of dielectric grease to the contact area to prevent future corrosion.
6. Reattach the ground wire and tighten the bolt securely.
7. Reconnect the battery and test the hazard lamps to verify the blinking has normalized.
