406 External Temperature Gauge and Fuse for AC clutch

Discussion in 'Peugeot 406' started by timfrommillstreet, Sep 30, 2007.

  1. Hello Folks,
    I'm looking to try to locate two items on my 2000 model
    year, Peugeot 406 HDI Estate.

    Item #1: Where is the external temperature sensor located?
    I've been told that it's in one of the exterior door mirrors but I'm
    not convinced. I belive that it's somewhere near to the engine
    compartment because the temperature reads normally as expected before
    starting the car but then after a number of minutes driving, the
    temperature begins to increase and generally arrives about 10 to 15
    degrees C higher thatn the actual temperature outside?

    Item #2: The AC is not working. I'm hoping that it's a simple
    electrical fault, either a connection or fuse that I can change and/or
    repair. I wish to know what fuses and where are they located that are
    associated to any parts of the AC system. My main suspicion is that
    the AC is not engaging at all when activated from the control panel
    and that the pump never engages as the clutch for the AC is never
    engaging. Any other ideas?

    I don't have a clue where the outside sensor is, is it important??
    The aircon has a low gas pressure sensor (somewhere ;-)
    which stops the clutch engaging when the gas gets low.. it's to save the
    compressor from damage.
    Or that's always been the cause on the aircons I've had that problem with.
    If you read this group at the beginning of summer there's usually quite a
    few of these requests, yours seems a little out of the ordinary being at the
    beginning of winter(?)

    The out side sensor is located in the near side mirror.

  4. Thanks for the help on the location of the sensor gauge. I guess it's
    woth a look. Does anyone know why the gauge would read accurately
    initially and then increase to a higher than expected temperature
    after a while of driving?

  5. Thanks Djimbo for the reply.
    I just got the car a couple of months ago and haven't had the
    opportunity with a job change to follow up on the AC until now
    Decided to begin to take a look at it last week. I've already checked
    and refilled the gas just a little - it was OK. I believe that the
    problem is more of a mechanical or electrical nature but that the
    coolant fluid is OK and that it's not leaking.

  6. Have you checked that the cooling fans are working when the air con is
    switched on. Air con wont work unless the cooling fans are working.

    Hello Folks,
    Hey, you ask a question, then don't believe the answer.
    The sensor IS in the nearside mirror, as in all Peugeots, and Citroens. If
    you look at the bottom of the casing, near the door, you will see a little
    dome. This is the sensor.
    They do all sorts of things when they go faulty.
