    What can be the cause of neither of my reversing lights working on my Zafira.

    Have checked the bulbs and their connections - no problem

    Have checked the fuse - no problem.

    Is there some sort of switch that kicks in when the reverse gear is selected
    - could this be the cuase of the problem?

    Any ideas welcome.

    Yes, if it's the same as Vectra then there is a reverse light switch on
    the gearbox which (on the Vectra) is prone to failure.

    Thanks for that - any idea how I check this out?

    I've not seen the Zafira one, but if you've got a multimeter, check for
    voltage between chassis and one terminal, then between chassis and the other
    terminal. Do this with ignition on (but engine off), and once NOT in
    reverse gear, then repeat IN reverse gear. If you get 12 volts on one side,
    but not on other, even in reverse, it looks like the switch. In which case,
    remove both connections from switch and check switch for continuity (low
    ohms scale) in Reverse and NOT in reverse.

    If you haven't got a meter, rig up a 12v bulb with a couple of wander leads.

    BTW, don't know if this applies to Zafira, but maybe there's a position
    adjuster on switch and it is simply not getting "switched" when you engage
    reverse. In which case wiggle it about a bit. If it looks a hopeless case,
    I suggest your remove switch and recheck it before buying replacement, just
    in case.

    If the switch looks OK, you'll need to trace the wiring from there to
    reverse lights.

    All the above assumes the switch is supposed to be switching he +12v line,
    not the 0v line.

    Unplug the switch and put the ignition on - get someone to watch them and
    short both terminals together with a paper clip or something. If lights come
    on then switch is faulty if not check one side is a 12v feed.

    D'oh. Dunno why I rambled on at such length, instead of a couple of

    Apols for missing the blindingly obvious... I'll fetch my coat now...

    Thanks for all the replies - there are all very helpful.

    Does anyone know where the switch is located and how I access it.

    thanks guys.
