Addressing Non-Functional Fog Lights on Tesla Model Y (2020-Present)

Step 1: Check the Fog Light Switch
  1. Ensure the Fog Light Switch is Activated:
    • Confirm that the fog light switch is turned on from the control screen or using the manual control (if applicable).
Step 2: Inspect Settings in the Infotainment System
  1. Access the Vehicle's Settings:
    • Go to the “Controls” menu on the touchscreen.
    • Navigate to “Lights”.
    • Ensure that fog lights are enabled in the settings.
Step 3: Visual Inspection of Fog Light Housing
  1. Open the Front Hood:
    • Release the hood latch and prop the hood open.
  2. Inspect Fog Light Assemblies:
    • Visually check the fog light lenses for cracks, moisture, or damage.
    • Ensure the fog light bulbs are securely fitted in their sockets.
Step 4: Examine the Fog Light Bulbs
  1. Remove the Fog Light Assembly:
    • If accessible, unfasten any screws or clips holding the fog light assembly in place.
    • Carefully pull out the assembly from the bumper.
  2. Check the Bulbs:
    • Disconnect the electrical connector from the bulb.
    • Inspect the bulbs for signs of burnout or damage (blackened glass or broken filament).
  3. Replace Bulbs if Necessary:
    • If the bulbs are burnt out, replace them with the correct type (refer to the owner’s manual for specifications).
Step 5: Check the Wiring and Connectors
  1. Inspect Wiring Harness:
    • Look for visible signs of wear, fraying, or corrosion on the wiring harness connected to the fog lights.
  2. Check Connectors:
    • Ensure all connectors are firmly attached and free from corrosion.
    • Clean any corrosion using electrical contact cleaner.
Step 6: Examine the Fuse
  1. Locate the Fuse Box:
    • The fuse box for the fog lights is typically located under the front trunk area.
  2. Check the Fog Light Fuse:
    • Use the owner’s manual to identify the correct fuse for the fog lights.
    • Remove the fuse using a fuse puller or pliers.
    • Visually inspect the fuse for continuity. A blown fuse will have a broken wire inside.
  3. Replace the Fuse if Necessary:
    • Replace the blown fuse with a new one of the same amperage.
Tools Required
  • Screwdriver set (Phillips and flathead)
  • Pliers or fuse puller
  • Electrical contact cleaner
  • Replacement fog light bulbs (specific to Tesla Model Y)
  • Multimeter (for electrical testing, if necessary)
Repair Instructions
Replacing the Fog Light Bulb
  1. Remove the Fog Light Assembly:
    • Unscrew and pull out the fog light assembly from the bumper.
  2. Change the Bulb:
    • Disconnect the old bulb and replace it with a new one.
    • Ensure it is securely seated in the socket.
  3. Reinstall the Assembly:
    • Place the fog light assembly back into the bumper.
    • Secure it with screws or clips.
  4. Test the Fog Lights:
    • Turn on the vehicle and activate the fog lights to confirm they are operational.
Replacing the Fuse
  1. Identify and Remove the Blown Fuse:
    • Use a fuse puller to remove the blown fuse from the fuse box.
  2. Install New Fuse:
    • Insert a new fuse of the same amperage into the slot.
  3. Check Functionality:
    • Turn on the fog lights to ensure they work after the fuse replacement.
Conclusion

If, after following these steps, the fog lights still do not function, it may indicate a more significant electrical issue, such as a faulty relay or wiring problem. In such cases, it is advisable to consult a Tesla service center or a qualified automotive electrician for further diagnostics and repair.
