XM rainwater leak?

Rainwater is finding its way into the ventilation fan situated in the passenger footwell.

Is this a known issue?

I am guessing that rainwater is being sucked from the rainwater drainage channel below the windscreen motors. I have cleaned the channel and the drainage holes seem clear.

I also think that the water collects in the air ducts supplying the heat exchanger. When I corner sharply the water flows along the airduct and hits the fan blades and makes a 'swishing' noise.

Are there any modifications I can make to stop this happening.

are you /sure/ it's rainwater ?

are you sure the heat exchanger isn't fubar ? happens when the antifreeze either hasn't been changed regularly or the wrong antifreeze has been used, setting up some sort of electrolysis which corrodes the innards of the heat exchanger*

you must always use the red OEM stuff, apparently.

Don't know about the XM, but on the Xantia this can happen when the plastic moulding along the bottom of the windscreen (which hides the wiper motor and linkage) comes unstuck.

On the Xantia, the bottom edge of the windscreen is directly over the heater air intake. If the moulding comes away from the glass, water can run down behind it and drip into the air intake, eventually appearing in the passenger foot well.

Might be worth checking.....
