Porsche Cayenne air conditioner leaking water into front floors on Porsche Cayenne

Some Porsche Cayenne owners report experiencing water leaking into the front floors due to a clogged A/C condensation drain. This issue is often caused by blockages that prevent proper drainage, leading to water accumulation inside the vehicle. Additionally, some owners find that inspecting and cleaning the AC rubber flap along the firewall on the passenger side is necessary to prevent further leakage. In more complex cases, using a leak detection device at the vents may reveal the source of the leak, which could involve removing the dashboard to check the evaporator. To resolve the problem, some owners successfully clear the clogged drain by lifting the front of the car and accessing the drain exit behind the suspension strut. Prompt attention to this issue is recommended to avoid further damage to the interior.
