Very strange problem. After heavy rains and the car outside, there is a lot of water on the floor on the passenger front seat. Windows/roof vere obviously closed. And it's not the first occurence. There is no water traces on the interior/windows/roof/dashboard. That means water could not have gotten into the car through the window or roof.

The only way of water getting inside I can think of is through the engine compartment somehow - that's the only source that cannot be detected from interior.

Any ideas?

 

Possibly thru the cabin air filter. The filter is within/behind the glovebox and gets its air from the passenger side hood vent. I've not had a problem there but yours may not be exterior sealed properly.

 

If you have a sunroof, that will be the cause.

How else could water get ON the seat? It doesn't climb.

The thread title says floor, but I now see seat cited. Has to be from overhead (sunroof?) if water is on the seat. Water can migrate quite a ways, but again would have to be overhead if seat.

So.... which is it, floor or seat???

 

Water is on the floor only. "Front passenger seat" only refers to location of the floor

So, cabin air filter is the only option. gotta check the glovebox...

 

Check your A/C drain...when it plugs up the water ends up on the passenger floor.

The A/C outputs a lot of water in cooler humid conditions......and it is on with the defrost.....

 

Yeah, that might be a problem. Where is AC drain located? Thanks!

 

Top of the engine area...behind the oil filter right up in the peak of the firewall opening

Looks like duck lips LOL

If you search there are some pics I posted eons ago

 

I searched the car, and I searched the forum for pics, no success... Any more clues how to find AC drain?
