440 air-con "recirculate" button bulb

Discussion in 'Volvo 440' started by Andrew Stephenson, Jan 11, 2005.

  1. Can someone tell me, please: in a "revised version" 440 (mine is
    from Aug 1995), when the bulb fails in the air-con "recirculate"
    button, how much needs to be replaced? The button, just to avoid
    confusion, is the one on the left (in RHD 440s, if that matters)
    which changes colour when pushed in.

    I stripped things down to where it looked as if the whole button
    assembly is replaceable, maybe even the switch. This seemed so
    wrong that I just put it back together. Searches on Google threw
    up nothing, FWIW. A big Volvo dealer's spares dept were baffled.

    I am baffled that your Volvo spares dept are baffled!

    It will be required to dismantle any switch to gain access to it's bulb, and
    this carries a high risk of damage. It is preferable to obtain a complete
    switch assembly.

    Prise off the blank switch cover at the right hand side of the panel. If
    this reveals the back section of a false switch, use a pair of thin-nosed
    pliers to pull out the back half of the switch.

    Reach in through the aperture with a finger or a hooked tool, and hook out
    the switch next to the blank just removed, pulling it towards you to
    withdraw it from the facia.

    If this is not the switch required, the wiring plug need not be
    disconnected. Carry on prising out the switches in this way until the
    required switch is removed, and disconnect the wiring.

    Dismantling a switch generally involves separating the front section from
    the rear body of the switch, which risks damage. Switch bulbs are usually
    wedge-based type, which can be pulled out.

  3. So was I. :-( But they _seemed_ to be trying to help, which is
    marvellous enough. :) The spares microfiche did not depict the
    assembly clearly enough.

    I have saved the rest of what you wrote but will snip it here.

    The "air recirculate" switch is not one of the big rocker types,
    as often used for major lights. Its push-button is round, maybe
    1cm across, and juts out of the plate which encloses the similar
    "a/c on/off" switch and the three environmental control knobs.

    I can strip it to where part of the recirculate switch mechanism
    becomes visible. But I cannot see how to dismount the switch or
    how to open it up to get at the bulb. It seems firmly embedded.
    The last time I had it stripped I was parked outside the dealer's
    spares dept and did not want to become too adventurous, in case I
    crippled the car far from home.

    I am quite happy to buy a whole new switch. All that's needed is
    the approved way of removing it.

    Thanks for your help.

    Hi Andrew,
    Re:
    I have a 460 but do not have that particular switch. But, if you have pulled
    off the knob and there is no nut visible, you more than likely must remove
    the panel and push the switch out from behind.

    It took me hours before I figured out how to remove the light bulb in the
    clock!

  5. Okay, I'll go take another look at the situation. The switch is
    not at all like any of the others, so maybe it calls for cunning.
