1993 90 water on floors

You state floors but you mean all floors? Normally only on one side at the time floors are flooded. Non drivers side: kit on front window bottom/cover is missing. Drivers side: via fuse box bottom. Also car was leaning backwards when raining heavily.

Good luck,

Years ago I had a flooded passenger footwell in my audi, ruined the computer. it was late fall, leaves and road debris had collected on top of the transmission, right under a plastic flapper valve that was supposed to drain water from the "wiper well". the water collected in the well and came into the passenger compartment thru the air duct feeding the heater core.

There's also the common problem of the A/C condenser drain reservoir plugging up. It happened to my 93 and 95 90.
