406 clicking noise

Discussion in 'Peugeot 406' started by Raymond Dalgleish, Mar 1, 2005.

  1. My wife's 406 T-reg estate has just started making a loud intermittent
    clicking noise from around the glove compartment area of the dashboard.

    The dealer says that it's either a relay or it's from the air
    recirculating fan. Either way, they say that it's not something to worry

    Any thoughts?

    The dealer is wrong. It is the motor that opens/closes the recirculation
    flap. It has stripped its gears. You can get to it by removing the glove
    box (remove the hinge pin either side underneath) and then removing the
    black plate behind it. The motor is to the right and is held in by two
    phillips type screws on opposite corners (it is also out of sight so you
    work by feel, laying on your back on the floor - or if you are lucky like me
    your son-in-law does). New ones are quite pricey so I have simply left the
    motor off with the flap open. I only ever used it when a smelly exhaust was
    in front. There have been many other posts on this subject, search in
    Google Groups under recirculation motor.

    The dealer is not correct (Again) - this clicking noise is almost certainly
    the air recirculation flap servo.
    You can test this by removing the pollen filter from behind the firewall
    under the bonnet and looking down, if the servo is ok then you should see a
    flap moving as somebody presses the recirc button.

    I had the same problem on my 'r' reg 406 and have chosen to remove the whole
    servo as replacement was around 80quid.

    I think we are talking about the same thing, I called it a motor and you
    call it a servo. We both took the same course of action. As a point of
    interest there are two versions of the motor and the earlier one is more
    like £120. There is also a difference between the motor on the standard
    air conditioning, which mine is, and the automatic air conditioning (climate
    control) so there are probably four different motors in total.

    Keith, WOW - what a complicated scenario just for a little servo motor...
    Well done again Peugeot.
    I call it a servo, because... well, it is really; It is a motor with gearing
    and load sensor.
    It's not the motor that has gone on mine, it's the big white plastic gear
    inside the servo housing, the motor has completely stripped it of teeth.
    When I bench tested the little blighter it took a heck of a strong load on
    the motor before cutting out, I suspect this is the reason the gears strip
    so readily - too much torque.

  6. Thanks for all of the replies. Given the cost and complexity of a
    repair, is there a SIMPLE way of disconnecting the motor/servo as I
    think that we can live without it.

    There is a plug a little further back, feel along the wire from the motor
    and you will come to it. It has to be unplugged anyway if you want to
    remove the motor. It is not easy to get out because it has a mounting that
    also has to be slid out of the bracket, but my son-in-law managed it by
    using brute force and ignorance. The cable is about 7 inches long.
    Further to Andy's reply. There is a small electronic device in the motor
    housing and I wondered whether it was designed to sense the increased load
    when the flap reaches the end of its travel and cut the power. If that is
    true, and it fails, the motor would just carry on going with the result that
    we have both seen.

    I said that there were two types of motor. I took pictures of my original
    and a replacement that I had to return (wrong one), you can see the pics

    Keith, Mine looks like your original one, I notice the electrical connector
    is different as well.

    The connector is different and so are the wire colours so I could not even
    try the replacement out. It came by post from a breakers in Norfolk, they
    were very good and gave me a complete refund, even postage. I was actually
    quoted £120 by a Pug agent just to buy it. Did you notice the verbose
    Haynes name for it?If Raymond is still following this a search on Google
    Groups on "recirculation motor" should bring up the original posts in which
    Nigel gave very clear instructions on handling this.
