    Brake light issue

    Hi. Just bought a 2011 3.0D XJ with a faulty rear light cluster on the drivers side. Side light and indicator worked fine, rear light and brake light didn't work.

    Bought a replacement cluster (ebay) and the rear light now works but the brake light doesn't. The passenger side works fine and the central brake light is fine also.

    Any idea what could be causing this. Appreciate it could be a faulty replacement cluster but is there anything else to try?

    Thanks!

    Hi. Does the reversing light work on that side. If not then I would check the earth connection.

    Not checked the reverse but will have a look in the morning. If the earth could be an issue, do you know where it is located?
    Thanks for the suggestion.

    I think I'd be getting a meter on it as the first port of call, before changing bits again.

    Unless the CAN controller is in the cluster itself, in which case I'd be taking one of the clusters apart...

    Does anyone know if the CAN is inside the light unit? In addition, do you know which wire should be the neutral or where I can get a wiring diagram so I know I am checking the correct wires?

    Thanks for all the input

    I do not offer advice, I only say what I would do with the set of circumstances presented. Your choice always.
