Brake light fuse blows when brake pedal is pushed. Removed bulbs one at a time trying to isolate the short. Could this be a brake switch problem? Why would the fuse blow?

    The fuse blows because of excessive current flow. I would troubleshoot that by installing a headlight in place of the fuse, putting a brake hold tool on the pedal to turns the circuit on, and then simply follow the current flowing through the circuit to the fault with a low amps current probe. Damage to the wiring harness that leads to the high mount brake light is common.
