406: Clicking Air Circulation Motor

    Just got this problem on 98 406 SL where motor clicks (presumably) because
    the limit switch is not working.

    I have disconnected the motor - which requires a contortionist to reach the
    comnnector - so I can have the air on external (I never use the recirc mode

    Q: Any sort of repair looks difficult for access reasons. How difficult is
    it, and what roughly are the parts costs?

    Don't know if I can answer your question--but I will add one of my own--is
    the clicking coming from beneath the glovebox? I have a 1998 406 SRDT, and
    ever since the dealer changed the pollen filter this constant clicking
    began. I had them look at it and they reckoned it had nothing to do with
    changing the filter; but they didn't fix the clicking either. Is this the
    same problem?

    Hi Bryn,

    This is quite likely to be the result of changing the pollen filter as when the
    filter is removed, crap can drop down into the heater airways. The secret is to
    hoover up all the dirt on the outside of the old filter first before taking it
    out. One cause of the dreaded clicking flap motor syndrome is a stuck flap,
    jammed by dirt. I've not had this but instead had problems with the hot/cold
    mixing flap on the right hand side of the heater.This turned out to be a problem
    with the electronics which for me as an electronic engineer was much easier to
    fix. I did take off the drive motor however. The re-circulate motor is on the
    left hands side as you sit in the car an is screwed onto the side cheek of the
    heater box. Once removed you can work the flaps by hand and hopefully dislodge
    what ever is jamming the flap. Make sure you re-engage the motor drive and
    flapat the right place eg moter set to fully open and the flap fully open.
    Otherwise you will have to take is all out again. (don't ask how I know this!!)
    Test it all before refitting all the trim.
    This is an awkward job = lots of time = expense if you ask your garage to do it.
    Definitely a DIY job I reckon.

    Good luck

    No, the flap is not jammed, works OK in response to the switch but when it
    gets into the fully open position, the motor does not stop. The clicking
    noise sounds like plastic gearwhhels skipping. I can't really see what the
    mechanism looks like without dismantling around the fascia whch I am not
    going to do in the middle of Winter. Looks like a time consuming job - does
    anyone know what needs replacing once you get there? The Haynes book does
    not mention it.

    One for lighter (and warmer) times I think.

    OK understood. I don't know how the motor is controlled at the ends of the
    travel. On the temp control motor flap, the electronic driver limits the current
    when the motor stalls but the freshair/recirculate flap only has to be open or
    shut and so possibly uses a limit switch, possibly inside the drive gearbox. I'd
    take it off the heater flap box and play with it indoors in the warm to see what
    happens and how it works.
    In the meantime turn up the radio!!

    I assssumed it was limit switches but it could be sensing the motor stall -
    in which case it is probably stripped gear teeth or something like that
    causing the motor never to stall.

    Easier to disconnect it, I don't think I could stand the graunching noise
    knowing that it was running continuously making repair ever more unlikely.
    Driving around for a few days on recirc has been very bad for misting up.
    Never use the recirc position anyway.
