could mean its not coming from above the firewall upper carpet. door seals perhaps..or sunroof seals. or the trail of water is just following a line where theres no contact with carpet.I checked after a couple of rains nothing...
left for a week a good rain up here in nor cal and the passenger side floor is soaked.
I have not seen the rocker panel drains? anybody have pics?
also i am not sure if it matters but there was no water on the firewall upper carpet only on the floor, gravity? or something else.
