Understanding the 2016 Ford F250 Left Trailer Light Fuse

The 2016 Ford F250 is equipped with a set of fuses that control various electrical systems in the vehicle, including the trailer lights. If your left trailer light is not functioning, it might be an issue with the fuse. Here’s what you need to know to locate and possibly replace it.

Fuse Box Location

The Ford F250 has two main locations where fuses are housed:

  1. Passenger Compartment Fuse Box: Located on the lower right side of the passenger side footwell. To access it, you may need to remove a cover panel.
  2. Power Distribution Box: Found in the engine compartment, this box is usually on the driver’s side, near the battery.

Steps to Check and Replace the Fuse

  • Ensure the ignition is off before checking or replacing the fuse.
