    Fan in XM Roof console

    Hi guys,

    Does anyone have any idea what the fan in the XM roof console, near the IR remote reciever is? We've always wondered what the whiring noise has been whenever the ignition is on (although you don't notice it once the engine is running). The last few days its become more of a squeak so we took the console apart to find this 20mm fan FULL of dust. Cleaning it all out appears to have quietened it down but what on earth does it do? The Haynes manual says it IS the remote sensor but we can see the sensor and the fan definately has nothing sensorish about it...

    Deka,
    That is weird why not post on yahoo xm site and let us know. Can't say I am aware of any noise in that area when ignition is on?

    Cheers

    Hi Derek,

    Are there electronics up there? Maybe it's like a mini CPU fan to cool electronics - the roof gets pretty hot sometimes...

    I did the same, removed the 'groaning' by removing the fan. I would like to know what the fan does???

    BTW my remote device is very aloof and works evey now and again.

    I'd still like to know what the fan does??

    Bob,

    Unfortunately our XM doesn't exist anymore... it was written off in November last year

    I did discover what the fan is for. It is a part of the air con system - the fan constantly moves air past the cabin sensor so it can get an accurate reading for the climate control.

    I can't remember who told me but it makes sense!

    Taking your remote apart and cleaning it with contact cleaner (from Jaycar) should help. Fixed ours for a while (it was a 1991 model).

    Derek.

    I can feel the need for some sticker slapping, Deka whistle

    Yes Bob if you'd like a sticker I can either send you one (or more as I see you have a froggy fleet!) or drop you in one if I'm driving through. I live in Killara.

    I reckon the part has a heat sensor, so the aircon part would make sense. I'll leave it out and see if I freeze!!

    But I reckon I am a 'sticker' candidate, the 406 coupe is a gem, a similar engine to the MX, the MX is certainly a surprize package and a fantastic unit.

    My next trip is down to Mr.Wong at Auto France to get the parts for the glove box lock.

    Thanks for your help
    Bob

    Hi all
    The little fan is part of the climiate control system. It is the sensor that measures the temp in the car. Seeya

    Correct, the fan blows cabin temp air past the temp sensor for the A/C. If it's noisy, like mine was, simply take it out and put a single drop of oil (sewing machine oil is fine) on the top of the shaft and let it run down into the bearing.
    I did this about 2 years ago, and it's still quiet and working fine.
    Cheers,
