Aaaarrrggghhhh!!!!!!!!!!!! Water ingress

[Burnzybubbles]

As above, it's happened a few times, I'm not sure where it's coming from, first of all the windscreen looks to be original, iv checked air con drain, only one left is scuttle drains, but I checked today after a heavy downpour and the scuttle wasn't full, I'm getting a wet front passenger footwell, it looks to be dripping off the underneath of the dash, first time round the fuse box was also wet on the passenger side, it's only happened after heavy rain and not when jet washing the car

The first time I noticed I got in the car early morning started off and had esp warning light on dash with abs as well iirc, didn't realise it was due to water till daylight and I looked into the pass footwell and seen the water, cleared faults and it'd dried out and everything went away.

I need to get it sussed as its not bad but it needs fixing, today it rained heavy checked scuttle as mentioned, looked fine, then I get in the car to go home later on and iv a small wet patch on the passenger mat
