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.
