why are my floors getting wet when it rains?

Hello, The sunroof area may not get wet when the drains are clogged. They go through the corners of the vehicle, so water can travel to many locations in the vehicle. Also, inside the doors are plastic covers that keep water from entering through the windows. If this vapor barrier is leaking, you may will find water in the floorboards as well. Lastly, water may be making its way in through the HVAC fresh air intake (under the windshield wipers), but I would doubt this since the passenger side is not wet.
