Resetting Auto Circuit BreakersWithout doing a "hands on" troubleshooting of your vehicle no one on this site can tell you specifically, what is causing the problem, or where to find it.

It has been my experience that all of the circuit breakers for automotive applications are self resetting.

Inside, they use bimetallic strips, and reset themselves when the circuit current overload, or short circuit conditions, has been removed/eliminated, and the bimetallic strip has cooled down.

IF your breaker is not resetting itself after a reasonable "cool down" period, then that suggests:

  • A short circuit condition somewhere in that circuit, or
  • An overload condition due to the addition of too much "extra" electrical equipment [like for example, a "monster" audio amplifier, or a light bar set], or
  • Replacement of an electrical device with one which uses much more current than the replaced device, or
  • A defective circuit breaker.
