I've recently bought a gorgeous 90 that was one owner and found out its been serviced @ Maxda its whole life when I brought it in for servicing. Yaaa!!
However, After a really hard rainfall I've found a puddle of water under the pasenger seat! I've inspected the door seals, sunroof seals, and at the foot under the dash of passenger area, looking for how the water got in, absolutely nothing wet except under the seat.
Where the heck is this coming from and how could it get in?
Help in Vancouver.

 

the water in my fc is like that but its not that bad. the water likes to drip down on the inside of the door and drips onto the plastic paneling thats on the bottom of the door. and usually it drips outside of the car. so maybe the panelling isn't installed right or is cocked. careful now we wouldn't want any mold in there. get some paper towels and put on the plastic piece and see how bad it runs in.
besure to carry a old towel just incase... its raining over here so don't feel alone with that problem.

 

the Sunroof drains through Hoses in the "A" Pillars..If they are Blocked or broke,you could encounter Water from the Sunroof Crevices coming out around the Bottom of the Pillar where the dash meets up..Make sure it is JUST Water also..If it is Coolant,then you have a Heater core leak.
