Hi all!
Got a puzalin problem, I have water running down both sides of my dash wich seems to be coming from behind the dash wich comes out over the kick panels and the water pools on the carpet on top over both sills, only seems to do it when car left over night and its rained?????

By the way my car is a classic on a 95 plate!!!

 

new one for me, have you tried doing a SN search/posting in the main area?

 

If its water coming from external of the cabin try using a watering can and only pour water slowly in areas (external) you suspect the leak originating. Try to locate tracking of water. Best done when car is dry on dry day so you ca see or feel the wet track / path of the water.

Arround the wipers the plennim / black cover tacks the water away to gutters so have a look around and under.

My son had a similar problem on his 'french thing' some of the water ingress was because the water run offs were blocked (leaves decomposing) poked with wire to clear and the plastic sheet under (water sheader) the door card had come away re sealed with silicon.
Water is a tricky thing to track. Is your car parked level, tail up or nose up.

Hope this helps.

 

Its parked level! Did notice yesterday that the water comes in when i move car after its bin sat all night can all so here the water running down as well, its not a big amount of water but its doing my head in now!!!
