Hi Marv. all the drainage holes are clear and I can see the water drain down them. There is no cable points under the houskng as iv had all this out to be able to reseal I dont think its the wind screen. Its wierd because when you take the pollen filter out of the housing you can see the water right down at the bottom justbefore what could be a fan into the cabin. Driving me nuts!
Can you see where the water has been tracking down the housing towards the fan? Might help to identify a corner which isn't sealed fully.
And is the filter itself completely dry?
I used the same butyl stuff as for the door seals, seems to have done the trick so far.
