why does my Tesla Model Y Current (2020-present) fog light keep burning out

Solution

1. Preparation

• Tools Required: Socket set, multimeter, wire brush, dielectric grease, replacement fog light bulbs.
• Disconnect the vehicle battery to prevent electrical shock.
• Allow the fog lights to cool down before handling.

2. Remove Fog Light Assembly

• Using a socket set, remove the screws or clips securing the fog light assembly to the bumper.
• Carefully pull the fog light assembly out of its housing without damaging any clips or surrounding components.

3. Inspect and Clean Components

• Check the fog light bulb socket for corrosion. Use a wire brush to clean any corrosion off the contacts.
• Apply dielectric grease to the socket to prevent future corrosion.
• Inspect the fog light bulb for any damage and ensure it is the correct type for replacement.

4. Test Electrical Connections

• Use a multimeter to check for proper voltage at the fog light connector; it should be within the manufacturer's specifications (typically around 12-14 volts).
• If the voltage is outside of this range, trace the wiring harness back to find any faults or shorts.

5. Reinstall Fog Light Assembly

• Insert the new fog light bulb into the socket ensuring it is seated correctly.
• Reattach the fog light assembly to the bumper using the screws or clips removed earlier.
• Reconnect the vehicle battery.
