    I have a problem with my roof, whereby it wont go down. i undo the roof clips, and they signal that they're open. I have my handbrake on and the handbrake signal shows. then i go to press the up/down switch and the roof warning light flashes -the windows don't come down and nothing happens.

    I've looked at all the other issues that cause a roof not to work and it seems that everything is in order, so i am now thinking it may be the up/down button fuse.

    does anybody know where this fuse is located - or more to the point the fuse box for the roof, and the number of the fuse (after looking in the 'wiring manual' i think it is SJ)

    I'm afraid there is more than one fuse associated with the roof. If the light flashes when you operate the up/down button, it must be getting power.

    Make sure the windows are both operating ok.
    If so, I'd check the luggage flap switch next.
    Then the left and right roof lock switches.

    Page D-46 of the wiring manual shows the inputs to the roof ECU.
    If nothing obvious works, the only way is to check the voltages on the connectors of the roof ECU, then operate the switches individually and check the signal changes at the ECU.

    By the way, just to make it interesting.... the roof ECU also talks to the window ECU. Both are located in the boot (roof ECU by the jack and to see the window ECU you have to removed the carpet).

    Good luck!

    have you tried pushing the boot open button, opening the boot fully, closing it and then trying?
    I had that for a while - fixed it by opening the boot and turning the two blue plastic bits until they popped back into place - the roof had somehow got mixed up.
