Pollen Filter Housing Leak

The housing for the pollen filter seems to be letting in water which in turn is leaking onto the front passenger footwell carpet. I put some silicone sealant around the outside of the housing.
Water should not be getting that far should it?

I spent 2 hours clearing out the rear sunroof drain tubes before realisong.

Sounds like a blocked / twisted / missing drain tube for the aircon - still active even at low temps

I've checked the A/c tube at the side of the centre console. Its well connected.
The engine wasn't running when I used the hose over the car for 20mins. It just seemed to be to much water for the aircon.
I could actually see upwards inside thew pollen Filter housing and there was water sitting in it. I have read other posts which mention the heater scuttle needing a mod?

I think you have been reading Discoduncs thread talking about submerging the bonnet in muddy water and where it goes. Maybe your plenum chamber drain is blocked.

I have no idea where it is, but I can tell you that a Fiat Punto has the same issue when parked under a tree for three weeks. The scuttle drain got blocked and the heater filled with rain water. I started the car and got sprayed with leaf mulch out of the dash vents

How removable is the chamber? Looks pretty well fitted to me!

I could be going mad!
When I took the pollen filter out for the first time, I could see right up through the housing as far as the black mesh with daylight on the other side.
Yesterday I could not see any daylight or the black mesh - just a grey panel that was sloping towards the front of the car.....?
I put the hose pipe on the front of the screen/bonnett area and couldn't get the leak to start again.

If you were looking upwards through where the pollen filter fits, then I think you saw the recirculation flap open the first time and closed the second time

"Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should."
Transgenic tomato anyone?

behind the lower glovebox - squeeze the to end hinges together and it drops down to reveal a black panel.
The pollen filter is behind this.
