Xantia- water under rear seat

SimonT · Post by **SimonT** » 29 Jan 2007, 14:00

Hi, anybody had any experiences where water was collecting under the single rear seat well. Can't see where it's coming in from but it's like a mini swimming pool under there!
Any pointers would be appreciated.
Cheers.
Simon.

Its a common problem - you should find other experiences on here.

I think the answer is that the plastic membrane in the door (plastic sheet - nothing more complicated!) needs sticking back on with seam sealer - or a substitute.

Are we talking rear door asd in tailgate or as in side door?

I'm managing to fond water coming in on a few estates AND saloons
so would like to nail it down myself!

MIND, WE'VE HAD SOME RAIN...

If its an estate,then most defo the tailgate membrain.I had this a few times till i fixed it for good.Water will come in around the rear wiper seal,& drain out at the bottom of the tailgate.But if the membrain inside the tailgate loses its seal,then the water will go straight in the boot under the carpet,& run along the load bay floor channels & under the rear seats.
If it is an estate,& it is the membrain,i did a post on here a year or 2 ago about the best way to cure it & what sealer to re seal it with.

I had this problem with my Xantia a few weeks ago. My mechanic told me that it is very common and caused by the drain from the sun roof being blocked.He recommended, that I push a length of wire (I used a thin knitting needle) up the drain. It is easy to find under the nearside rear wheel arch, a small plastic pipe protrudes from the top above the wheel. You can feel it, I could also feel the mud caked around it!! A few prods with the needle and I got a cup full of cold water up my sleeve. I could then pour a pint of water into the rear of the open sun roof and watch it pour from the drain. Atrotious weather has followed without a drop of water finding it's way under the seat!! I hope that you can be as lucky. If it is the off side it does not look as simple to get at it from under the car, but I was told thast I could push a thin piece of wire from the drain at the rear of the open sun roof. Thankfully it has not been necessary.
Good Luck!!

I'll give that a go thanks - hadn't though of actually looking for the rear
drain pipe and had conveniently forgotten a similar fix on my Xm!!

Sadly, I seem to forget more things than I know!! Must be getting old...

Ok thanks, I'll have a look tomorrow (weather permitting!)
It is the nearside back seat so hopefully will be that side drain too. Cheers.
I love this forum!

Hi nipper - welcome on board -

Your problem is wellknown - try a play with the search function. You should get several earlier postings as result. Note that you need at least 3 characters as search criteria.

What's the possibility that it's getting into the heater past the scuttle panel then running into the back footwell?

Yes, very, very possibly and the foam under the carpet will allow it to creep up to the seat well. Had it happen.

Also, another place it can get in is through the rearlight clusters. All the tailgate water runs down over the tops of the clusters and if the gaskets are not perfect, water will run in the boot and then into the rear seat trays. I cleaned the gaskets and smeared them with silicone grease. Seems OK now.

next time you lift the tailgate on a wet day, just see how much water runs down over the lights!
