Water leak - footwell & A-pillar?

I have been suffering a water leak for a couple of months. I tracked one leak down to a leaky screen. The water was running down to the corner of the dash and dripping onto the floor.

After a search on here I sealed the screen with some suitable black mastic and that leak went away. However I am still getting wet floors.

I have spent some time this weekend really looking for the 2nd entry point and I have found that the water is seeping through the seam that runs vertically down the footwell wall, just to the right of the drivers legs, next to the bonnet release catch, behind the trim panel. It appears that the original seam sealer is cracked and water can seep through.

I'm obviously keen to stop this before it does any serious damage. I am assuming that water is getting in or around the A-pillar but I can't work out how.

Any thoughts/ideas/solutions gratefully received.

Cheers,
Andy Howlett.

Mine leaked around the grommet for the bonnet release cable, the water ran along the cable to its lowest point then dropped on the floor, took some time to find it as I was looking for a hole directly over the puddle, small dab of RVT sealant and it’s been ok since

First check all the possible entry points from the engine side, pedals, wires etc. Probably not this but worth checking. It could still be a part of the screen that is not adequately sealed. Also check that the drip holes are present at the bottom of each door. It doesn't sound like heater box because that would drip on the passenger side.

Mine was a leaking heater valve.

in the end i found that there was a very small pin hole under the channel that holds the bulkhead to bonnet rubber, this had allowed water to seep inside the base of the screen and rotted the area where the inner wing joins the bulkhead.

Are heater valves prone to leaking? I think that I might have the same issue.

Yes. Worth checking.
