Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect and Clean Battery Terminals
  • Remove the battery terminals using a socket wrench.
  • Clean the terminals and battery posts with a wire brush to remove corrosion.
  • Reattach the terminals securely and ensure a tight fit.
3. Check and Replace Fuses
  • Locate the fuse box (usually under the dashboard or in the engine compartment).
  • Identify the fuse related to the dashboard lights using the fuse diagram.
  • Remove the fuse and check if it's blown (the metal strip inside should be intact).
  • Replace any blown fuses with the correct amperage rating.
4. Test and Replace the Dimmer Switch
  • Locate the dimmer switch on the dashboard.
  • Use a multimeter to test for continuity; if faulty, remove the switch by unscrewing it.
  • Replace it with a new dimmer switch compatible with the 2015-2020 Ford F-150.
5. Inspect Wiring and Connectors
  • Visually inspect wiring for any signs of wear, fraying, or disconnections.
  • Use electrical contact cleaner on connectors to ensure a good connection.
  • Re-secure any loose connectors and wiring.
6. Alternator Testing
  • With the engine running, use a multimeter to check the alternator output (should be between 13.8V to 14.5V).
  • If the output is low, consider replacing the alternator.
