[bigrayray]

I have a 2000 ES 300 plantinum edition 90k miles. Noticed the drivers side rearf floorboard wass soaked. Then itg sprfead to the passenger side rear floorboard. No rain the day we found or the few days before. Anyone have any ideas

There are three possibilities for where the water is coming from, and it may have been there for some time and you've just now discovered it.

The first place to check would be the rear drain tubes for the sunroof, assuming that your car is so equipped. Over time the plastic drain tubes can crack or come off of the end of the channel that the sunroof runs in. Since the rear tubes run down the C pillar (between the rear door and the rear windshield) before exiting the side of the car between the rear bumper cover and the quarter panel. Leaking water will end up on the rear floors. To check the drain tubes will require that the headliner be dropped down enough to check their fastening and condition.

The second place to check would be the rear windshield sealing. Water seepage there can end up on the rear floors, or in the trunk.

Thirdly is the sealing of the rear tail lights or the trunk lid. To check the tail lights will require pulling the trunk side and rear panels, lifting the carpet, and looking for evidence of water trails that flow forward when braking the car.

Good Luck!

I had a similiar problem and it was fixed by cleaning the A/C drain underneath the car.

The a/c is what I was thinking. How do I go about cleaning the drain out?

[griffon]

You need to locate the the opening under your car and then either shoot some air up in the hole or use a hanger or something like it to unblock the drain.

I would take it for oil change, while car is up as griffon says follow his instructions.

not hard...
