i was just checking for the cell phone that well udner the seat and i found out that the carpet under the passenger seat is soaked with water....
any ideas as to how the water can get there? drivers seat is fine.

 

Could be anything. You need to be a lil more specific. Car? Year? Sunroof?etc?

 

THere is a huge groment under the battery (in most year civics)that might be missing. If not that youll need to pull up the carpet to look. It may not be on the floor and may be up more on the firewall near where the tire can shoot water in it. Good luck.

 

this is 2001 civic coupe, no sunroof, its not wet under the front floormat but its realy wet under the seat and under the rear seat floormat

 

unfortunatly I am not to familiar with 7th gens........yet. I would start by pulling up the carpet, it has to be easy to find if it is in that small of an area. Prob some1 put an amp under the seat at one time. Are you orig owner?

 

Other possibilities could be 1) Have you done a stereo install recently and not installed firewall grommet properly? 2) Have you checked all the door seals including the trunk/hatch? 3) Have you had a winshield replacement recently? 4) Does your AC drain through the floor and is the drain still intact? 5) Fresh air intake could be causing the problem? 6) Is there a sweet smell in the car (anti-freeze). I'm assuming this only happens when it rains. Does the leak get worse when driving, if so I'd check the firewall areas. Hope these help cause the last thing you want is water then rust [sm=wtf.gif]

 

there is no sweet smell, i didnt use AC, car has a stock audio system and its not wet under the front passenger floor mat, its only wet under the rear right passenger floormat and a little bit under the front passenger seat. where is fresh air intake? windshield was not replaced as far as i know and i dont see any water damage on the ceiling or any traces of water on any plastic parts. when i open the door i see some water accumulation on the door rocker panel but my 2004 civic has the same thing and the water does not leak inside.

 

does it only get wet when its wet outside?

 

yes, only when its wet outsite

 

it could be getting into the fender through the door
