Moin! After my other thread was trashed with clever speeches about clogged water outlets, interior filter types and fire videos, I open up a new one. I am a lantern parker and often had the problem that I had water in the fan box. My retrofitted interior filter was soaked, so I got back equipped, but the problem remained. So bad, that when I ran the fan in the morning, I could hear it shoveling water. Of course, I did the procedures counter I also looked at the rubber seal under the plastic box, but that was all perfect. When I had inside frozen windows in the winter, I had to act. I disassembled everything, wiper and cover down, raised the moose on the driver’s side and simulated the rain with a watering can. The water runs down the disc, over the wiper to the side groin rubber and then into the mo there it goes on and drips exactly on the intake box edge…tja and then it runs comfortably into the fan box. I have created remedy, in which I glued a rubber edge to the box, which keeps the water away, since then is calm. I actually had the problem only if it stands to the passenger side slanting, otherwise not, there seems to be a different way to look for it. Still I am from the open construction of the intake channel with the opening upwards, e No matter if now with filter or without, little enthusiasm. You could have done better, a small cover with increase would have been enough. With some more pictures to make the course more understandable.
