Leaking Micra - Wet Footwell - Help Needed

Joined here as maybe someone can help 

Im a non driver but my other half owns and drives a 52 plated Nissan Micra Tempest

Of late we have experienced a problem in that when it rains we get a wet floor in the passenger footwell

The water seems to come from somewhere behind or under the glove box area (the drips come about where the driving controls would be is they where on that side, is that makes sense)

The heavier the rain, the worse the drips

Now I have cleaned out the gutters at the side of the door

I have managed to use a thin piece of wire to clean these out fully and they seem to run off to the drain behind the wheel ok but still we get the leak

I have no idea what else to try and hope someone here can help (mainly in idiots languages as, like said im a non driver, and maybe even with pics)

Anyone able to solve this ?

Ok, now with added photos

What with the torrential rain we have had these last few days the car is soaked

A local garage my other half got to look at it said it was fixed, but this was when it was dry, so obviously the issue never showed, so again im trying to fix myself

Last night, as the rain fell, I tried to angle my camera into the space where the drips where coming from and attached are my findings 

The one pic is very blurred, but the water is dripping from the area of the nut (of which my finger rests on and is near in the pics) and the small "nipple" next to it

If I pushed on the nipple the flow of water sped up !

Any clues or suggestions ?

Will do

I managed to remove the wipers and as such the cover which sits at the base of the windscreen

Under this cover is what I can only describe as a channel / drain

Along this channel, directly in front of where the passenger seat is and pretty much above where it leaks is a raised piece of metal making what looks like a well into the car (as a complete idiot I would guess this is where the car takes in the air for the air vents etc)

Curiosity got the better of me and I poured a quarter of a pint of water into this "well" and sure enough the water came out exactly where my drips where.  

Above this well and in front of windscreen was a small "clip" which I guess is for the windscreen so I used some clear sealant and went around this and also all along the bottom of the windscreen

Sods law, its not rained since
