I have a two door 01 Accord. Everytime It rains or gets washed, it seeps through. My floors end up getting soked and at times it gets into the seats. I thought it was just because my Sun Roof was brokening, but it doesn't always come from the top. Never head a car doing this. Not sure where to go for this.

 

Car was prolly In an accident. First take a hose spray the car with water and locate where the leak is coming from. It can be from the rubber strips or a drain hole being clogged.

 

I'd check the drains for the moon roof. They can get clogged and cause the water to get inside the car. There are four, this pic only shows examples

 

Take a cup of water open the sunroof and pour the water into the channels in the four corners. The water should run out by each wheel. If you have one that doesn't the drain is clogged.

 

Sunroof drain and door jamb seals are where I'd start.
