I'm trying to exclude potential causes of a leak that seems to be causing dampness in the rear compartment floor. I've looked at it seems like 1000 forum posts and google searches.
Fundamentally I'm stumped on two points...
1. Is there a way to access the drain hose from inside the car. I can get to it from the bottom but doesn't appear to be anything happening there. I've read in at least one place that tehre s some sort of panel in the passenger floorwell that allows access, but I've just taken the thing apart (centre console completely out, trim around the gear area completely out) and still can't work out if this access exists... I really just want to check it's not blocked from the top...

2. If it's not the above, I'm thinking it might be the sunroof drains, but I'm 100% sure there is no issue with the front ones. Which leaves me wondering where the rear ones are and how you get to them. Doesn't seem an obvious way to get to them without removing the sunroof completely...
After that I'm stumped.

Anyone have any insight on these two? Or an idea of anything else it could be (I've also taken the rear bumper off and had the compartments in the boot up but the dampness seems to be isolated in the rear footwell with a little coming forward.

This is from first generation RX, but suspect your vehicle has similar location of drain tubing. Look at pictures and see fix.

Thanks for that.
That makes me believe that there is pretty likely a rear drain pair of pipes on the suroof. Question is where is it on the 2nd Gen? And how do you access it? As I said, I've taken the boot containers out. I think the designs are very different. e.g. In the 2nd Gen the spare wheel is attached underneath the car, not accessible from inside the boot...

I have posted 4 images from a RX400h 2nd generation. I believe that this sunroof would be identical to RX330 and RX350 2nd generation. I can clearly see the front drain pipe but cannot see any rear drain pipe.

Hope this helps.

Happy for anyone to correct me if I am wrong.
