Passenger side leak under glove compartment when it rains

[Rob P]

We just purchased a 2008 Porsche Cayenne S (still under warranty) and as we were driving it home it began to rain...by the time we drove the 3 hours home, we realized that the passenger side floor mats were soaked. When you put your hand up it and behind the very bottom of the glove compartment, you can feel it is all wet. We did a some research and saw that it might be the drain hole that is clogged from debris, however we aren't aware how to clean it out or where to even locate the drain (there are several holes that look all the same). When we called a nearby dealership we were told that if it is clogged from debris, it isn't covered by the warranty. any suggestions on how we can figure out exactly where it is coming from? Pics of where to look? Thanks!

Please do not post the same question over and over - I have deleted the other two posts with the same content.

If you remove the cabin filter you will see a rubber hose connected to the air box, thats the drain for the climate control plenum. I used compressed air to clear the drain.

If its rain water from the windscreen and sunroof drains, the clogged rubber bungs are in the bulkhead up under the wheel arch mouldings (mouldings are quick to take out, sods to put back) one each side. I clear mine after every winter. You can often hear the water "slosh" when cornering if the drains are blocked.
