I have a 2003 Boxster S and found a puddle of water on the carpet floor of the passenger side. I have been reading about clogged drains and that they are relatively simple to unclog but I cannot locate them. How can I locate them? If I decide not to take care of the problem any idea what a shop charges?
Draining holes are small and they are reachable after putting roof to service position on the half-way. Metal cover must be fully up. You can test drain system by spilling water and checking, if all water goes out on the street in front of rear wheels. If not, you 're in big troubles because some "clever" Porsche engineer placed control unit of alarm on the floor under the drivers seat. Water in cockpit is a big probleme therefore. I never thought, that someone could be so stupid and invent such position for sensitive electronic device.
