Servicing butterflies

[PaulZR]

Have just been out for a couple of hours to investigate but have been driven in by hunger and crap weather.

Am still thinking that it is the little fan at the back of the control unit that's causing the problem. Only thing that's causing me to doubt this is the fact that it keeps spinning for a while after you kill the ignition, but the noise stops if the ignition is off.

I sussed how to loosen the entire unit from the dash though your method sounds simpler (I ended up taking the stereo out and depressing each of the four retaining tags in turn - painful).

What I can't figure out is how to slide the unit out of the dash past the indicator stalk - the stalk seems to prevent the thing from leaving the dash. Am I overcomplicating this? I can see that the fan should be detachable on its own but don't have a spanner small enough to loosen the two retaining nuts and would rather have the whole thing out and on the kitchen table!

If the noise isn't the CCU fan, it maybe one of the blower units behind the front bulkhead, a right royal pain in the arse to get to.........Open the luggage lid, remove the cover 2 screws IIRC and find the blower fans in there left and right, You may well want to look up the Rennlist forums, this has been posted over there before with answers on how to eliminate the noise.

Does your have pollen filters like the 993 ?

If so I had a bad squeek in mine and it was one of the fans touching the filter in the housing. I shaved a bit off the filter and all well since.
