Water Under Back Seat Mystery...

[christopher 5 1 Cars]

I keep getting water under the back seat. Sometimes there is quite a lot under there.

 

Any idea how it gets there? The seal to the tank sensor seems to be in correctly, so I can't think from where else??

 

Any ideas??

back lights, sunroof, window/door/tailgate seals etc. sit in the car and get someone to hose the car with water to see if you cant find where its coming in.

You mean you think the water is coming in from the boot area and getting under the back seat that way? Is that really possible?

 

Everywhere else seems to be dry..sometimes a tiny bit of water in the boot but nearly nothing. I have no sunroof either..

Water can enter from pretty much any opening or gap in sealant etc, and it will always gather in the lowest part of the car, usually under the carpet.

 

First thing you need to establish, is where the water is coming from. Its unlikely that a leak will enter from the front of the car, not wet that part of the carpet, but make a pool of water in the rear. So therefore, i'd start at the back of the car with the most likely of place, sunroof and tailgate.

My guess, it'll be coming in through the boot somewhere, boot seal or holes for the tailgate wiring in the body, then running under the rear seats.

the back window seals in one of my cars seemed to of shrunk with age and wouldn't seal properly, used to leave a puddle big enough to farm salmon under the seats

i spent the other day sorting out my leaks . I was getting a bit of a soggy carpet and puddles under the rear seats and a lot of wind/road noise from the back of the car. Firstly i went to sort out the rear 1/4 windows. i've always noticed that the seals had shrunk dramatically. After reading a post on here , i think by Tom Fenton if my memory is correct who mentioned taking the seals out and stretching. I removed the glass and bashed the seal on to see how bad it was and found a good 3 inches or so needed to be found!

 

it took a fair effort of keeping the seal warm infront of the heater and jamming the seal under your foot and stretching, working your way round. It took a fair few refittings to get it a nice tight fit. cleaned up the opening , the seal (with silicone lube) and window. with everything refitted it looked so much better with the rubber seal now sitting neatly round the opening. did both sides and went for the obligatory test run (any excuse!) . wind/road noise almost non existant hooray - next mission fit rear speakers.

 

While fitting the rear speakers with the c pillar trim off it starts to rain . I'm sitting in the boot with the lid up and it starts to rain and low and behold a trickle of water starts running from the top corner of the boot seal down and running down the shell. you would never see it with the trim on. I took the boot seal off and cleaned everything up and squeezed the grips on the seal further together. All seem well now after testing with a hose.

 

hope this helps , Al

One more place to check - where the rear spoiler attaches to the top of the tailgate. Water can get in through the holes here and run down 'inside' the tailgate and out through two little holes in the bottom l/h and r/h corners of the tailgate. I don't know why these holes are here but if there is water getting into the tailgate somehow (also possible through tailgate glass seals) they allow the water out and into the boot, making the carpet wet (and if a big leak, possibly transferring to the back seat area).

If it colecting under your rear seats, then my money is on the rear side window seals. Anything to do with the boot and you would at least have a wet boot underlay before it got anywhere near the rear seat wells.

thats what i would have though , but the water from the boot seal top corner found a track down onto the wheel arch and followed it down to the seat well. very little water was resting in the boot.

 

i've done a pic of the other pug with a rough idea of the direction of the trickle. the car was sitting pretty level at the time with me sat in the boot . so a bit down in the arse!!

all my seals were good when this happened to me

i traced it to the rubber wire cover that the goes between the top of the boot lid and the roof

the lazy alarm fitter had run a wire out of it stopping it from sealing properly

Rear window seals, the water gets in and runs down behind the trim. It's very difficult to spot unless you remove the side trims.

Lift the carpet up and you'll see it trickles from there into the rear passenger footwell.

Interesting I think I have a similar issue, did you ever cure it?

If you look at the boot you'll see a couple of drain holes in the bottom edge, these let the water in and quite often run's towards the front of the car depending on the angle of it when parked and fills up the back seats

just cleaning up the seals and refitting on the boot. there was also a lot of dirt/old leaves etc in that channel which i think was making the water run where it shouldnt. seems ok with a hose and at the moment everything is still dry.
