Hi, my name is***** are no serviceable fuses for the brake lights and license plate lights.

Expert:  Marty replied 11 months ago.

Those lights are controlled by a signal acquisition module. They are fused internally within the module.

This problem is usually caused by broken wires in the wiring harness at the left trunk hinge.
