For weeks now, with the incessant rain, my rear passenger side footwell is completely flooded... not just damp, but absolutely flooded. The mats are absolutely sodden.
I did have a problem with water in the boot and read on the forum about the high level brake light seal... and sure enough mine was compromised, so I removed and refitted the seal and it seemed to cure the problem.
But I am at a loss where to start looking for a leak in the rear footwell as there is no openable window or door - so does anyone have any ideas? The only thing I could think of is through the high level brake light again if it is just running to one side?
Oh, the other thing my daughter noticed when in the back was that the back seat was damp... but I cant believe its coming through the boot seal onto the seat and then only into the passenger footwell.
I was thinking about removing the high level brake light seal and replacing with a bead of silicon sealant as used in bathrooms.
Has anyone else had this, or any thoughts where to start?

Reason: vehicle details added
I also noticed that the rear seat felt reasonably dry except where it meets the upright section which comes up behind your legs and meets the seat when you sit in it... although the carpet on this vertical section is dry... I also checked the boot and this is dry so I dont think its the high level brake light.
Also, the carpet under the front seat feels dry!
Any advice on where to start would be appreciated.

Reason: Additional info.
does you drivers window drop when you open it and lift when you close it.
if it does close the door get some masking tape run a tape line down the front of the window in line with the windscreen trim and one along the top below the roof line. open the door see how much the window drops. it should be 5mm along the top edge and about 3mm on the front edge from what i remember.
also get a bit of paper fold it in half put it between the door seal and where the window would come up against it close the door and you should feel a light but firm resistance as you pull the paper out
if the window is not dropping or lifting check your fuses in the passengers side foot well F19 left window motor
check your door seals are correctly fitted to
this is where i would start, i would also get a wet vac in there to ASAP or go the petrol station and use there big hover :-)
if you think it may be the high level brake light stick tape around it seal the gap to check it first i would not use a sealer personally as the trend to trap water and will cause more problems than you trying to fix and becomes more of a pain to remove
Some good ideas there... yes the windows do drop as you open the door and rise once shut - but I will check the seal with some paper.
I dont think the high level brake light is the cause as the boot is completely dry now and has been for some time.
A colleague at work has suggested checking the drain holes at the bottom of the door is clear - so I will also look at this.
I read some more today on some other forums and several people suggest using an ultrasonic leak detector (or smoke pellets). I have found this and think I might get it anyway - but if anyone has used one before I would like to know how they got on...
I saw them using something similar on Wheeler Dealers for a window leak that soaked the footwells on a DB7, smoke machine I think they used, and it was coming out round the door glass at the top between the glass seal and roof seal, his cure was a right bodge, stick some string behind the seal to make it thicker and press on the glass more, instead of fitting a new seal of course.
No problem be careful, we use smoke pellets and smoke machines at work, and the smell lingers in the trim and seats so be careful.
tbh if you boot is dry I would not think it's the brake light, it may be the rubber trunking has come out that gies between the boot lid and the body.
But to get that far forward and that much I would say it's around the door seal area.
I would get it all cleaned up and get the hose pipe on it blast it round the window and door area, site inside with a torch and get someone outside with the hose
Do you have a sun roof ? also in the boot open up both access panels for the rear lights check in there for water in there.
Pop up your rear seat and check under there it my be coming in through the access hole for the fuel probe/pump
It's possible that the door drains are blocked but there are a few holes there. It's worth checking, the door panel is easy to get off.
Thanks Marque & James... I reckon I have got quite enough to be going on with now
I took the plunge and bought a Sealey P44 Ultrasonic tester which is being delivered tomorrow. So if it does what it says then I hope it will find the problem.
I had a closer look at lunchtime today and pulled the passenger door seal off and there is signs of water under it - also when I opened the boot, where the plastic trim which runs around the inside of the bootlid joins at the corners there is signs of water there - when I moved it quite a lot came out, so it looks like the brake light is still leaking. I just cant believe that the water is travelling from the boot to the rear passenger footwell without getting the boot carpet wet.
At the weekend I will strip it right down as I replaced the interior for a half leather one when I bought the car, it shouldn't take too long to get the rear seats out - that way I can get a good look.
Thanks for the great advice and I'll let you all know how it goes
It wasn't only the wiper grommet... there is still a flood. Using a hose, I found the rear boot seal was leaking - so replaced that and that's good now...
But this morning another inch of water
So stripped the rear interior panel out and there is water sitting in the small gulley between the rear nearside window glass and the metalwork its bonded to... but even with a hose on the door I cant see where its getting in. Also in the gap where the inertia seatbelt unit is fitted, there is a water trail running down here too...
Any thoughts? Nearside door rubber - or could it be leaking between the car and the window?
Running out of patience now, so any help or thoughts would be appreciated.
