Water Leak- Passenger Floor-Not AC problem

[Sharklet]

Hi - would appreciate any thoughts on this.
Have an 05 1.3 Petrol VVT RHD in the UK (so AC not needed so do not think it is a clogged drain!)
The Passenger floor is soaking - have checked that water drains from the windscreen ok (original screen). Floor Seals are in place and cannot see any leaks from Door/Passenger Window.

Have removed Glovebox and Carpets as far as possible (how difficult are the carpets to get out!) and run a water hose down the screen and after a few minutes can see water trickling down the angled panel forward of the passenger floor about 3-4 inches from the tunnel.

Have read somewhere that the AC/Pollen filter housing seal can deteriorate - any ideas how easy this is to get to and would this cause this?

Or any other ideas appreciated.

Thanks

there is an inlet below the cowling (at least on the 06+) that lets the fresh air into the hvac system...i would take off your wiper cowling and see if its leaking in thru there..

Thanks for that - will check tomorrow - if it ever stops raining !

At least you don't have to shovel rain...

Finally think I have located where the water is coming in - a black hard plastic panel on the angled panel forward of the passenger floor - the white polystyrene panel locates on this via a peg.
Image attached; problem is what does the panel do? does it just clip out; presume the forward side is under the wheel arch panels. Will try some sealant around it, but would like to know what it is for.
Any clues ?
Thanks

On our LHD US cars we have two white plastic plugs like that on either side. They don't go through to the outside, but lead to a cavity between two layers, so I assume they were access ports that were used to prime the metal.

I had this problem with my wifes Yaris a couple of years ago. Check for leaves etc. which may have got into the heater. There is a small drain tube under the heater on the passenger side which goes through the floor. This was blocked. I cleared it from under the car and resealed both ends. Did not have any more trouble. Hope this helps.

I know there are flaps to expell air so when you close the door it doesn't just bounce back open.

Those are behind the rear bumper, under the tail lights.

Mine just started leaking so these hints are really appreciated.
It was always fine, no issues and then between one rainstorm and the next it started puddling on the passenger side. Luckily I've got WeatheTech mats otherwise I'd never seen it against the black carpet.
Thanks again AND thanks for keeping the posts available/searchable.
What a huge help.

LOL. I've read a few threads on other sites with an argument about weather going on between someone in a U.S. state bordering Canada /or in Canada and someone in a U.S. Gulf Coast state. Each one is giving the other grief about the shortcomings of the weather in their area. Each of the few of these I've read has ended the same way....with the Gulf Coast person writing "At least we don't have to shovel humidity" .
