The heater/airconditioner box under the dash has a drain hose to allow condensation to drain when the air conditioner is running. If this hose gets plugged, rain may accumulate in this box also (if it's raining heavily), as it comes in through the fresh air intake.

Look on the engine side of the firewall, probably on the passenger side, for a hose coming through the firewall that is not connected to anything. It is usually short, has a 90 degree bend, and the open end is down. Make sure that the end of this hose is not plugged.

Does it just leak when you are driving or does it leak when parked as well? The reason I ask is if it leaks when parked, you can eliminate a floor pan leak, or a leak that gets water from the wheel slinging it up in the wheel well. These things can be a pain in the *** to find. If it is not obvious, like torn, worn or out of place weather stripping, then I usually take a pressurized hose to wet only one section at a time and narrow down the source of the leak. It could be the seal around your windshield, stripping around the door, or even water getting inside your door and somehow finding its way to floor by draining along the inside door panel. Good Luck! I hope you find this to be very helpful!

Testimonial: "Leaks when it rains and is pretty severe. I actually can scrape the water off the carpet after a heavy prolonged rain. New windshield and it still lea"

i had the same problem. Flushed the sunroof drains, replaced the windsheild, and weather stripping on passenger and driver side doors. Car is still leaking. No one can figure it out.

Look for a plugged drain at both rear side panels. Water from the top can enter the car, but it is then discharged out thru drains. If the drains are clogged, you will have this problem. Same for any other Toyota convertible.

The AC evaporator units have a drain hose that runs through the floor because condensed moisture is a fact of life with AC units. Yours is plugged. You will have to get under the vehicle and look for the hose where it comes out, then take like coat hanger wire and clean it out, It is somewhere in the vicinity of where the passenger foot well meets the fire wall. If you have to raise the vehicle to get under it, make certain you have it safely supported. If you don't have the stuff, drive the passenger side wheels up on a good curb and use some cardboard to slide under.
