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

After renewing the door seals i found i still had a leak passenger side which still gave the results of the door seal but actually turned out to be the access hole seals for the window glass clamps,

just a heads up, they look sealed but i took my door card off whilst it was raining today and saw the drops physically dripping from the rubber seals for the access holes,


silicone smothered on the seal & internal seal and all seems good!

Ive noticed leaks on mine so will be re-sealing soon. Thanks for the heads up on that, i'll make sure i check the access holes :)

Just wanted to say a word of thanks to DubSteve68 for his detailed photo guide. The level of detail provided gave me the confidence to change the butyl, which had corroded away around the speakers (like almost everyone elses!).

Now waiting for it to rain to see if my attempt has been successful.

Just done my door seals, thought I had done a very nice and through job, what do I find in my socket set, only one of the bloody bolts from the carrier, I could have screamed, no way of telling which door its from.

Is it the end of the world if I dont put it back??

Many thanks for the detailed guide DubSteve68!

Are you talking about the bolts that holds the door together (helps secure the sandwich??) I sheered one of mine off when I over tightened the Bolt. I wouldnt worry - just check the door when it rains - I put Newspaper in my footwell to see if it absorbed any water.

Yep it was one of those, funnily enough I sheared a bolt too on one of the other doors. I am eagerly anticipating rain now to see if things have improved.

Seals were not so bad that water was coming into the car yet, but the sills were covered every time we had a downpour so I decided to do the fix before the weather gets worse and it became an issue.

Good idea - so no need to check under the Carpet? Mine was sodden took ages to get it dry hence testing it with the seat out and the carpet lifted up etc... when it rained . My seal had degraded just under the speaker (passenger side). I didnt do all my doors as I only had a leak on the passenger side - mine seems to be resolved!! Touch wood. I do check the other doors after a severe down pour!!

No I dont think it has gone as far as managing to get into the footwell yet, could the carpet feel dry but be wet underneath then?

Well mine wasnt particuarly wet on surface but you could here the squelching when you applied pressure (try giving your carpet CPR and see if you hear/feel any thing). There is an underlay that is rather thick which absorbed all the water initially. I think the water drips down the side and into the underlay rather than through the surface of the carpet. If that makes sense. I went on holiday so the car was static for 2weeks when we must have had terrential rain. You could smell the damp and see it in the Windows.

You could be different but I HAD to remove my seat and the plastic trim to get at the underlay and remove it from the car to dry it out. Removing the seat also meant disconnecting a cable so now my Air bag light is permenantly on - needs to be reset when I send it in for a service.

Well, I performed "carpet CPR" and the passenger side underlay is indeed soggy! I really can't be arsed to take the seat out and remove the carpet so im gonna try a dehumidifier first and do that as a last resort.

Cheked the footwells so carefully when buying the car too as I knew of this problem, I just didnt realise it would not be evident on the surface if it had ingressed.

Cool at least you found it - will check mine again when it rains!! Taking the seat out wasnt too much hassle but I had to remove it from the car via the rear door (in reclined position). I also had to cut the underlay out as its in one piece and spans both footwells (so I could dry it on the radiator in the house). I used newspapers to absorb the excess water in the car.

My Car was starting to smell of damp & the squelching was really bad so I had to get on top of it quickly as I was worried about the electrics. It took most of the afternoon to seal the door and pull the car apart. I left the underlay over night on the radiator and few hours next day to put it all back together again. Just got the annoying air bag light to resolve (later).

I think I will patent "Carpet CPR" ;)

From memory I think I left the car apart on the weekend and put newspapers where the carpet underlay was to see if the problem had been resolved when I fixed the door. Newspapers were dry after down pour so put the underlay and car back together after that.

my car was static for 3 weeks during heavy rain while i was in the usa, came back to find soaking wet footwells front and back both sides. :(

Got my front two doors sealed with butyl tape at my local bodyshop for £60 :) the old seals were proper rotton by the speaker area both sides . Used a wet/dry vac and sucked out a good 2/3 litres of water from the carpets and then finished off with a dehumidifier over a weekend. carpets are dry now apart from one small section of the driver front footwell where i can hear a slight squishing sound if i apply pressure, but i think that will dry with time. Now i got to see if anymore water returns :whistle:

As has been said by most, big thanks to the DubSteve !

3 of my 4 doors had gone, badly !

Soaking wet footwells on all but front passenger side.

Just followed the guide, job jobbed !

Although I did have to wait to do my final door as the single role of tape wasn't enough (I re-sealed every inch of every door)

Got my local Eastern-European Car hand wash team to suck out all the excess water with their industrial sucker upper and then shampoo the carpets.

Car all now bone dry and smelling fantastic.

Haven't been so happy since I first took ownership.

:D:D:D:D:D:D:D:D:D:D:D:D

Laura did you manage to download the Doc??

Hi Shiney - Im in Locks Heath!!! Great idea getting the Eastern Europeans to suck the Water up and Shampoo it - where did you get that done?? I keep on checking my other Carpets but think Im ok now then again I used Sealant rather than the butyll tape.

I'm in Bordon now mate, I have a local one up the road in Bucks Horn Oak, they did an awesome job.

They're all over the place these days mate, just look for a hand car wash that does valeting and I guarantee part of that will be carpet shampooing, if they do that then they can suck up your water, give the carpets a shampoo and get it all nice and dry and smelling pretty !

Thanks to the guide and advice on here I have hopefully fixed 3 of my door seals with butyl strip and will be doing the last one soon.
I only thought the o/s/r footwell was wet but when I peeled the carpet back the n/s/r was wet too (not as bad) so I went the whole hog and removed the front seats too and discovered the front footwells were also wet underneath (again not as bad) ... the carpet and top layer of the underlay does a good job of hiding the water!
I decided to remove the underlay from each footwell which required some strategic cutting in places andpartial removal of the plastic door trim along the sills and partial removal of the centre console where the gearstick is ... was a pig of a job but there was no way that hidden water could be sucked out or evaporate ... I used a rug doctor to suck the water out of the carpet and undelay before drying the underlay overnight.
To avoid the airbag light coming on disconnect the battery before removing the seats and don't reconnect the battery or try key in ignition until the seats are back in.
