Water leak into footwell - dodgy seal info and DIY repair guide (Image links dead)

Just buy the butyl stuff off eBay. There's loads for sale on there and no chance of it failing if applied correctly.

I still have a full roll left over and that's me done all 4 doors.

fancy doing mine with it then :D

This is an excellent guide! I have had water leaking in through the pollen filter, front passenger door seals into the footwell and the rear offside footwell. I sorted my pollen filter leak out by filling in the gaps between the pollen filter cover and where the pollen filter cover sits with silicone. I haven't had an issue.

Last week I finally got round to sorting out the front passenger and rear offiside door. I too removed the door card but NOT the door panel. I just applied silicone directly over the thin foam that was visible. I hope this works but by the sounds of it, other people have tried this method and have failed. Its rained a bit and so far not a drop on the door sills but today its chucked it down so will check in the morning!!!

My biggest problem now is trying to get rid of all the water that has been absorved by the carpet in the rear offside footwell. All I can do is keep wiping it with a cloth and wringing the cloth. I need to put the window down as I drive if the weather permits!

You may need to seal around the speakers on the aux carrier etc as well as it can leak in there too!
Another possibility is the door seals block the drain holes in the door bottom when the door is closed this is why you sometimes get water coming out of the door bottom when you open the door,you can mod them by cutting a bit away where they line up with the drainholes -there is a thread on hear somewhere.

If you dont dry the carpets properley you will never get rid of the damp,the rears seem worst as the floor pan is lower allowing the water to collect,i ended up doing the following,

Remove rear seat base (unclips)
Take off plastic side trims,door treads & covers over front seat runners,just a few Torx screws
Push front seat right forward
Pull up carpet as far as you can,exposing underlay felt which will be sodden,this holds loads of water,i cut mine with a stanley knife where it goes under the seat and removed it hung it to dry and put a fan heater in car to dry floor etc.

i know this sound s a bit involved but it beats taking the seats out (althoughthat is not a big job) its all the rest that you have to remove as well!

Hope this helps:)

door seal

its not the door electric panel seal that is fauly its the design curve of the car door...if you spray your garden hose onto the door the rain runs down the doors/window seal but due to the curve of the door the excess water drops onto the speaker pod and escapes around that area, look at your panel bet there is some water marks there, also the 2 black stoppers that you use to adjust the window into the elctric window frame can also allow slight drops of water into the footwell area....to solve this and to never happen again, get a tough plastic bag and some duct/grey tape. cut the bag around 320mm by the length of the door( but a bit longer) and tape to the back of the electric panel, tape to the thickness of the tape below the 2 black stoppers, and cut nicley around the window runners and tape up the cuts as best you can , fit the electric window panel and fit the new plastic bag nicely into the inside of the door before fitting the panel...this plastic skirt then catches the excess water coming down the window and it doesnt touch the electric window panel or the speaker pod, and the water runs in the doors gutter at the bottom and escapes as it should...problem solved....mentioned the 2 black stoppers cut slightly thicker piece of plastic bag to the size of the black stopper area/width ,and the height of the bottom of the stopper to the top of the electric panel, tape the top of the plastic strip to the top of the electric panel you might want to get a thin piece of tape or string attached to the bottom of the bottom of the thin piece of plastic strip....fit the panel along with the new plastic skirt, put all the panels bolts in loose, then refit fit the window into the runner, but before you pop back on the black stopper pull your thin bit of tape or string to feed the thin plastic piece down until its covering/past the black stopper area, then refit the black stopper, again any water running down will run down the plastic and not hit the black stopper...retighten bolts and finsh of door panel...........no sillicone needed at all...sounds a ball-ache to down but its a piece of piss

You're right, that does sound like a ball ache! :) What it also sounds like is what Vauxhall used to do with their doors, they use a similar waterproof membrane to channel the water away from the interior panel and down to the gutter. Problem is their membrane goes brittle and breaks up, and before long you have a rusty door. I would expect whatever plastic bag you use would do the same thing over time, and you'd end up back at square one.

I'm not trying to say that your method won't work in the short term, and it is quite creative, but considering you've already got the panel off to do all that work, it just seems easier to use the butyl tape and have it sealed permanently. And it's the removal of the panel that's the most complex part of the fix, actually applying the tape is a two minute job.

Ironside: Good point about the speaker bit. I didnt seal around the protruding cone but I'm not getting any leaks into the speaker or from the speaker itself. I just siliconed around the perimeter of where the thin existing foam is visible.

Anyhow it pissed down the other night like I said, and opened both the front passenger and rear offside door and not one pool of rain on the door sills :) However the sills are not bone dry. When I run my finger on the sills its moist and it feels like running your finger on a cold coke can. I guess this is just normal though?

Thanks for the tip on drying out the carpet much appreciated. Its winter so its a bit difficult to do that at the moment :( Thanks for your response and help mate.

After 7 trouble free years (okay apart from the pollen filter which was done in the first six months of owning!) i've joined the leaky door seal army!

I'm following the excellent guide from DubSteve68 and ordering this and this today!

Fingers crossed for a sunny (okay i'll settle for a non rainy - after all I am in Wales!) day next week to tackle this head on!

Has anyone any recommendations of what to put on seat fabric where there is mold growth?

Some say spray vinegar, but don't want my car to end up stinking like a chippy.

Wish I found this site before I pulled some trim off to try to get underneath carpets - managed to get to the "foam" under the carpets and have washed / dried as smelt like some kind of mushroom morgue. Still got to put that all back together, but going to apply the "dubsteve butyl" fix, dry and dehumidify first.

hoping the dryout will cure the mold, but quite worried about it, things like that freak me out ....

If the mould is as bad as it sounds then I'd be tempted to remove the seat fabric and give it a hand wash, then drip dry before putting it back on the car. At least then you can use a decent detergent.

(By the way, mold and mould is more based on what country you're, and since the UK use mould for both meanings it sounds like you were right the first time!)

Recently discovered I have this problem so VERY grateful to find such a useful and informative thread. I'll be arming myself with some butyl cord, spare clips and tackling the job asap!
Given it seems to be such a common problem I say shame on Seat for such a shoddy design, it would certainly influence my decision whether to buy another Seat - definately not.
In my case I'd noticed the water on the sills and, what I thought was slight ingress of water on the top of the rubber mats, but it's obviously more serious than that and has been soaking into the sound deadening material for some time which is sodden. I went overseas for 3 months leaving the car locked up and parked on my drive and on my return had an extensive pond in both passenger side footwells and the interior was completely covered in disgusting mould - seats, steering wheel, trim, seatbelts, carpets and smelt like a mushroom farm! I've had to sponge everthing with a bleach solution and clean the upholstery to get rid of the stubborn mildew stains. I've taken the seats and carpet out to dry it all out and get rid of the smell. Hopefully following attention to the carrier door seals my problem will no longer exist.

Can anyone say if this would be suitable for re-sealing the doors? I am going to do mine at the weekend..

Cheers,

mmm... if you believe the dimensions, (6mm wide, 5mm thick) then ok, - however the picture clearly shows something thats more like 1-2mm thick.

If you get whats in the picture then id say its not suitable.

However its also fair to say the stuff that most use is TOO thick (its say 10-12mm and round rather than flat) and works better by flattening it out a bit.

Gents, when i was taking off the door panel to my front passenger side of the car, I broke 2 clips. I need to get some new ones and know where to get them from thanks to one of the posters on this thread.

The question is, has anyone else broken clips and not put in new ones and have found the door creaks when the car is in motion or is it just that I haven't fitted the card back on properly? Its winter and I dont want to take my door apart again. cheers

Ive just found this thread and it explains why my Leon has been misting up in the winter. I have just followed the advice and used silicone to seal the panel, it was soaking when I removed it as was the rear foot well behind the drivers seat. For a problem that seems so common I am surprised that SEAT have not done something more about it. Thank you for the advice, Ill see if it sorts the problem out over the next few weeks.:)
