2003 civic coupe gets wet at floorboard while sitting in or driving in rain. no visible water running down interior firewall or kick panel. mostly wet at center and front left corner. can someone help me please?

Thanks, Jack

 

Have you had a windshield installed in the car ??? Have you run any wiring through the firewall on the driver's side ???

 

Common issue is the urethane that seals the windshield has dry-rotted and now leaks water.

 

no, this problem started out of the blue.

 

thanks, I may have to take it to a trim guy to inspect.

 

I’ve never seen the windshield urethane dry rot. That stuff is nearly indestructible.

I would guess it’s coming through some body filler behind the fender.
