I was thinking with all the torrential rains we've been getting that perhaps it might be a wise idea to check the passenger floor, since I've seen mention of flooding on that side. I pulled up the floor-mat and found the floor was wet, as in quite wet. What to do? First I looked under the hood. The windshield drains around each of the hinges on either side of the hood.. and it basically looks like it just runs down inside the fender housing and dribbles to the ground. I released and pulled up the plastic cowling on the passengers side that seals the bottom of the windshield. If you remove the two twist locks, you can bend the plastic up enough to see what's going on without having to remove the entire thing (which would require R&R of the wiper arms..) I found a formed foam dam that was supposed to direct water down into the fender innards - (crappy design IMHO) and it was totally plugged with several handfuls of leaf munge/nuts/twigs. I scooped out as much as I could, then I got the industrial shop vac and vacuumed out a lot more. I finally made sure the passage was open by poking a large diameter (10 gauge) insulated wire down the water path. I checked the drivers side just for fun, and it's harder to get to since the wiper linkage is in the way, but it looked clear on that side. I also vacuumed out the little drain in the center recess for the wiper eccentric linkage for the port side wiper. I then attacked inside. I took down the kick panel under the AC, and pulled off the AC drain hose from the HVAC housing. It appeared free, but to make absolutely certain, I used my #10 wire again to poke out until I could feel and hear it in the engine compartment. I then pulled the carpeting out from under the door sill, and the port side kick plate. I found there is a large wire bundle going through the area, which is located in an elevated plastic tube/tunnel on the floor. As it goes up the firewall, it turns into a cloth wrapped cable. I opened up the tube/tunnel, and happily, all was dry there. What was wet was the massive amount of foam rubber that forms the bottom of the carpet and the lining for the floor. There must be 2" of foam rubber under the carpet. Several towels were soaked as I sopped up the water, squeezing the foam rubber to make it release the water. The water was clear and no-smell, so I suspect it was from the HVAC drain. I then took my industrial shop vac and sucked a lot of water out of the foam rubber. While I was in the area, I decided to add a drain. The lowest point of the floor has a body plug in it. I can't get to the other side of the plug since it's above the extra trim that the Titanium package has (the extended body sill trim).. so I cut a hole in it. As I continued sqeezing water out of the foam, it happily drained right out the hole I made. Since it's above the sill trim, I suspect unless I start submerging the Cayenne, it isn't going to cause any leakage into the vehicle. For those who haven't had this happen, or those who have (it's not uncommon) - I'd suggest making the drain hole. Only takes a minute, and can be done with a pocket knife.. I'm going to check the rear seat area, and the port (drivers) side to see if the same drain can be done. It might be sufficient to simply make the X cuts in the plugs, that would allow any small amount of water that gets in to drain out, and would restrict ingress of water if the floor gets submerged..
