My 2001 honda civic has been getting wet each time it rains. The back floorboards are soaken wet if it rains hard and long enough.. the front began to get wet also. I realized that my back seats aren't wet, but if I stick my hand in between the seats (where the seat belt it, the bottom of the seat belt is wet) I lifted the back seat down, and the back of it isn't wet, nor is the trunk. I'm thinking this has something to do with my sunroof drains being stopped up?? How does my floorboard get wet, the seat belt, but not the actual seat or back of the seat?? Very confused! If it is the drains, how do I go about fixing this?

Nasty problem. Condensation on windows may cause you to have to scrape ice on the inside of your windows, if you live in a cold area.

Check the condition of the sunroof's seals and clean with silicone spray.
