Hi hoping someone can help me it's driving me round the bend. I've had a wet footwell forints and it's beginning to drive me crazy. I have tried the following.

New Ariel base and gasket and ensured it's sealed.

Sunroof seal replaced and sunroof and checked.

Sunroof drain now exits the car onto the road.

Door rubber seal cleaned and refitted

Plastic sheet behind door card renewed.

I've had the carpet and underlay out and can't find rust or holes.

The car is hardly driven and this occurs when the car is stationery

[jayrs]

Could be coming in via windscreen rubber.
Could also be a rust hole in the floor, wheel arch, or on the bulk head at the too of the wheel arch.
Also they can rot on the bulk head right up behind the dash by the windscreen rubber.

If your loosing coolant, could be heater matrix

[willowandmikey]

Thanks for replying.

The floor is solid no rust at all.
The wheel arch is also rust free.
Bulk head is rust free also.
Not loosing coolant.

It's weird the carpet gets wet by the reinforced plastic heal plate but isn't wet on the surrounding carpet. But the roof isn't leaking.

There is a tiny rust bubble on the windscreen surround. Do you think it's worth getting auto glass or such like to take the screen out and put it back in

[jayrs]

That's your call mate, the rust could be worse behind the rubber, and it might not even be that.
The drain holes in the sills could be partly blocked also?

[Boostjunky]

Also worth checking the heater matrix too surely !!!!!!

Had a pinhole in one once and was a mare to trace were it was coming from until the heater fan jammed and when changing it noticed the leak

[willowandmikey]

It doesn't lose any coolant at all so I assumed the matrix was ok. I have checked the drain holes and rodded them they are working well and in any case the drain pipe is now completely outside the car and not inside the sills any more

[willowandmikey]

I'll check the matrix anyway so I can tick it off the list

[willowandmikey]

I think I'll leave the windscreen alone I think you're right jay I'm just asking for grief

[jayrs]

Lol it can be mate, but it is/can be the source of water leaks, but you can see what it's like and if it's likely to be that?
Might be worth stuffing some tissue between the dash edge and the windscreen rubber, try get it down pass the rubber and against the bulk head, if waster is coming In there you should find it.

Worst case, dash out, sound deading off and try trace it, get a hose over car and try find where it comes in.

Might even be the drain holes on the bulk head blocked and it's backing up and finding its way in via wiring loom grommet or something

[willowandmikey]

Ah the bulkhead the rubber flap bit is clear is there anywhere else I need to check

[jayrs]

Not the rubber flap bits, there's a hole right where the turret meets the bulk head.
Tbh because if the design if the fiesta bulk head even if them holes are blocked it shouldn't make a difference.
One thing I over looked, if the car is parked on an angle say up a Kurb, or on a hill where water gathers or cant run freely away, it could build up and find its way in via a grommet or such like.

Also, I've seen people state problems with wet foot wells which had come down to the fact the cars been used so much during wet weather, the carpet was wet from water from shoes.

But it don't sound like your problem as yours is fairly wet isn't it?

What I done years ago when my passenger foot well was getting wet, is I cut the carpet out of the foot well and ripped up the sound proofing from the floor and off the bulk head and put news paper down and looked to see where it was getting wet when it rained.

I know that's extreme, but the carpet stank, the sound proofing was fcuked and needed changing anyway lol
My leak came down to windscreen seal and a bit of rust

[willowandmikey]

Not soaking wet just wet to the touch. But the carpet all the way round it is damp it's where your heels would be. I hardly drive it TBH it's not been out in the wet I'm going to double check the drain holes and seal the grommets with mastic.

Jay thanks for taking so much time to help out it's driving me round the bend

[jayrs]

Mate I know how much it can drive you mad lol
Hope you find the cause of it one way or another before the carpet starts to stink

[ZetecsTurbo]

Try the smoke method mate, hire a smoke machine or u can buy smoke bombs from somewhere, set it off in ur car with doors and windows shut but bonnet open, wherever smoke comes out fill it with silicone

[Boostjunky]

Has your drivers side door rubber/seal shrunk like most seam too as this can cause ingress under heavy rain

Failing that I would say its from front screen only way of checking is by dash removal so you can see it coming in whilst someone sprays it with a hosepipe

[rob pace]

strip the whole car and find out! i know its a pain but is the only way!

[reithy]

Have a look at where all the wires come into the car for the fuse box, mine is leaking there where someone has puncture it to put other cables through.

[Lee jst]

As jay says above I am having the same problem just taken the dash and sound deadning out my car and I can see rusty water marks running down from the windscreen seal inside the car going down the bulkhead so took the windscreen out to look further and where the seal sits on the inside of the car there is surface rust at the two bottom corners so there obviously water getting in. So maybe worth getting the screen and dash out to get a proper look about it mate

[willowandmikey]

Does sound like a plan I'm hoping my mojo will return
