406 Clicking noise

    Hi everyone.

    My 1997 Peugeot 406 started to make a clicking noise from
    behind the glove-box, in the passengerside. (I have a LHD
    peugeot 406), so the noise is from the right hand side).
    The clicking noise seems to be 1 click per second.

    Could it be the ventilation fan or something around this area??

    I noticed that when I turn on the recirculation of the air, the
    noise stops.

    I really hope someone can help me with some ideas.

    Kindest regards

  2. You are hearing the motor that opens/closes the recirculation flap. It
    strips its gears and then keeps on running. The expensive cure is to have
    it replaced, about £140 gbp (200 euros ?) to buy plus fitting charges the
    cheap way is to make sure the flap is in the open position (you can see it
    if you remove the grid and filter beneath the windscreen wiper) and then
    disconnect the motor. I did this and the only time I regret it is when a
    smoky car is in front of me. This problem has been covered fully in
    earlier threads, search Google Groups for "recirculation motor" +peugeot.

  3. Martin,

    This is a common fault and there is a past thread of correspondence
    about it on this newsgroup. You could search for it on Google News.

    The clicking is caused by wear of the nylon gears on the servo motor
    that opens and closes the flap that controls whether or not the air is
    recirculating in the car.

    There are basically two options. Replace the motor, or disconnect it.
    When it happened on my wife's car, I opted for the latter. Whichever you
    decide on, it's good to have very small hands as it's difficult to get
    at the motor.

    Check the past threads for full details.

    Hi again.

    Thanks for your replies.
    How easy is the motor to get out? or disconnect?
    And how is this motor accessed??
    My haynes manual does not describe this :-(

    By the way, when disconnecting it, how can I make sure
    the flap is in "normal" position?

    Hope you guys can help me a this, as its really annoying.

    Kindest regards

  5. This is all from memory: we traded in the 406 last weekend.

    First lift the bonnet and remove the plastic grill/trim just under the
    windscreen on the passenger side of the car. This will reveal the air
    intake. Look down into it to see if the flap is open or closed. The
    servo motor will probably still work enough to open it if it is closed.
    Don't put the grill back just yet.

    Remove the glove box. It's held in place by two white nylon pegs that
    act as the hinges and simply slide out. Once you have that out of the
    way, you should be able to see a small inspection plate (~10 cm square)
    that is held in place by one (I think) Torx screw (can't remember what
    size). Remove the plate and look up into the dark void above using a
    torch to light your way. If you feel around, the main object up there is
    the motor. If you are not sure that you have identified it correctly,
    turn the re-circulation on and off a few times. You should be able to
    feel the motor vibrating slightly.

    To disconnect the motor, feel around for the pair of wires and
    disconnect them: it's a simple pull connection. BUT FIRST, check that
    you really have left the re-circulation flap open. You can now put the
    grill back under the bonnet.

    I never tried to get the motor out, so cannot help you there.

    Once the motor is disconnected, the light on the re-circulation botton
    on the dashboard will still work. That's good when you come to sell the
    car: no awkward questions from potential buyers.

    Hope this helps,

  6. I found the most essential piece of equipment was an agile son-in-law, as
    you are working under the glovebox in front of the passenger, at times on
    your back.

    You should find that the flap still opens and closes (closed when the light
    is on, open when it is off) but the motor continues running and clicking
    when the flap reaches its limit of travel. You can also see the flap by
    removing the grid outside under the passenger side wiper and the filter
    below it.

    Remove the glove box by taking out the plastic hinge pins. Behind it there
    is a black panel, secured if I remember correctly by one screw. Remove the
    panel. The motor is through the hole and round to the right, put your hand
    through and you will find it. Operate the recirc button and you will feel
    the motor running. If you want to remove the motor it is held by two
    pozidriv type screws, in opposite corners. Otherwise follow the wires and
    find the plug, it is tough but will pull out. I tried to get a replacement
    motor (also apparently called a servo) from a scrappy but could only get the
    later type which will not do. This link will take you to pictures of both
    the original and later type motors.

    Hope this helps

    Thanks for the tips from both of you. :)

    I will try and find a replacement, and then try and replace
    the motor..
    I hope everything will go smoothly (otherwise, I might return
    with more questions, hope that is ok :)

    Kindest regards

  8. If you are replacing the motor you will need to be aware that there are two
    separate motors depending on whether you have automatic air conditioning
    (climate control) or bog standard manual. Your car, like mine, should be
    the early model and should have the type of motor referred to as original in
    the web pictures. I decided, after having problems getting a replacement,
    not to put the motor back and, to be honest, I haven't missed it. I don't
    think I used it hardly anyway.

    One other point. A number of people have said that you can buy the gears
    for the unit from model shops and, apparently, there are matching ones in
    Range Rovers. I do not, however, think that changing them will make a very
    lasting cure as there is an electronic device inside which I suspect detects
    the increased load when the flap reaches the end of its travel and cuts the
    power. This is only guesswork but it seems the sort of thing that is done
    these days and I could not find any other system for detecting when to stop
    the motor.

    I will be interested to hear how you get on.

    Good Luck,

    That's small motor which changes the air-intake (recirculating) when you
    press the button. It is broken and you need a new one (expencive!!)
    This is standard repair on 405,406...)...
