Issue: Ambient Lighting Not Functioning in Tesla Model Y
Tools Required
  • Tesla Model Y owner’s manual (for specific fuse information)
  • Fuse puller or needle-nose pliers
  • Diagnostic tool (optional, for advanced diagnostics)
  • Multimeter (optional, for checking voltage)
Repair Instructions

Step 1: Adjust Touchscreen Settings

  • If the settings were incorrect, adjust them as follows:
    • Access the Controls menu from the touchscreen.
    • Set Ambient Lighting to On and adjust the brightness slider.

Step 2: Update Software

  • If an update is available, follow these steps:
    • Connect to Wi-Fi.
    • Select Install Updates and follow prompts.
    • Allow the vehicle to complete the update and reboot.

Step 3: Perform a Soft Reset

  • For a system refresh:
    • Press and hold both scroll wheels until the Tesla logo appears.
    • Wait a few moments and check ambient lighting functionality post-reset.

Step 4: Inspect Ambient Lighting Components

  • If the problem persists:
    • Remove any coverings or panels that obstruct access to ambient lighting components.
    • Check all wiring and connections for tightness and any visible damage.

Step 5: Fuse Inspection and Replacement

  1. Locate the Fuse Box

    • Identify the fuse box location in the owner’s manual.

  2. Remove the Fuse

    • Use the fuse puller to extract the fuse associated with the ambient lighting.
    • Inspect the fuse for continuity (a blown fuse will have a broken filament).

  3. Replace the Fuse

    • If blown, replace it with a fuse of the same amperage.
    • Reinstall the fuse in its designated slot.

  4. Test Ambient Lighting

    • Turn on the vehicle and check if the ambient lighting is functioning.
Conclusion

If the ambient lighting still does not work after performing all diagnostics and repairs, consider contacting Tesla service for professional assistance, as the issue may be due to a deeper electrical malfunction or a problem with the central control unit.
