I have water on the passneger side floor board of my 93 SI when it rains heavily. I know there was a TSB about this for 92-95 civics and when I searched there was many people with the problem and no fix.

How do I fix this? it suposedly is a seam at the fender/fire wall?? can any one cive me some details I dont want to just go spreading silicone all over

 

Pull back the carpet and find the rust.

 

I dont believe its coming through rust in the floor since I have never seen rust on my car. some seal or some thing has failed

bump for more help

 

Same problem. I installed new carpet, color change, but before i did i gutted the interior and undercoated the whole thing, now theres water, what gives?? Any ideas??

 

look for any rubber plugs and things. etc... that could be it, jus an idea. Peace!
