Brake light dead
My taillight is burning, but the brake light does not seem to work on either front or rear brakes. What are the odds that both switches have died? Surely not?
2010 model with about 38 000 miles If it makes any difference... my horn is dead too (but they die all the time) |

The big question is why? Sometimes fuses just "blow" through poor manufacture, fatigue and bad contacts/corrosion. It could however be a fault with the horn, either of the stop light switches, the rear light cluster or in the wiring. Try replacing the fuse. Turn the ignition on, but only try operating one thing at a time. This will help you isolate the fault (if there is one). First try the front brake, see if the brake light works and, more importantly stays working. Repeat with the rear brake alone and then, finally try the horn. If the fuse does blow at any point you'll have a pretty good idea which component is the culprit. If everything stays working, then you're good to go. If the fuse does blow during one of the tests, then you'll need to isolate exactly where the fault (short to earth) is in what ever component/wiring that's is causing the blown fuse. It could of course blow straight away as soon as you turn the ignition on, in which case the short will be in the supply wire to one of either of the brake switches or the horn switch |

As you suspected. Fuse 2 was blown. I replaced with spare, horn is working as well as the rear brake switch. The front is still dead though. |

What you could do to check this is trace the wires back to the connector and detach it. Use a multimeter connected across the switch side connector terminals to check the operation of the switch. Also bridge the two loom side connector terminals with a piece of wire and check to see if the stop light comes on. This will verify the switch is dead and that the wiring to/from it is OK. |

When I squeeze the front lever, I hear a clicking noise near the fuse box. Not sure if thats normal or not.

Can you pin point the noise? Is it coming from one of the relays for example? |
