Ive searched and checked everything before posting.
I got a 95 SC400 with a water leak on the pass side.
There was well over an inch of water in the front and rear floorboard.
I got the carpet out and had my wife spraying everything on the outside and no water seemed to come in.
I checked the evap core hose and made sure it was clean.
I checked the sunroof drains and they are all connected.
I checked the plugs in the floor and theyre all there.
I blew through all of the sunroof drains with a blow gun and the air was coming out somewhere under the car so I assume that they are clean.
The water got in in a bad rainstorm on a trip to florida which I really cant recreate here in st louis.
Is it possible that this was a fluke and isnt gonna happen again or is there something im missing?

Thanks for any help you can offer.

 

Man... You seemed to have covered everything that I can think of. Could it be a seal around the door or a leak from the windshield? Just a thought of something else to check.

 

did you leave your pass window cracked or something haah call i can think of

 

It is not a door seal or windshield seal. I checked those as well.
Not unless the window was just slightly cracked but I dont think so.. surely there would be wind noise or something.
I pretty much gave up and Ill wait to see if it happens again.. I dont know what else to do.

 

It could be that if you used the fresh air-conditioning it was pulling in a crazy amount of moisture in FLA, and it couldn't drain it all off, so the box overflowed out of the cabin intake box.

Also, if the evap core drain is clogged it might not drain fast enough to prevent overflow out of the cabin intake.

If you use recycle a/c it doesn't have to pull as much moisture from the air, and the system won't create as much moisture.
