Water leaking into drivers footwell

Just recently I have had water leaking into the drivers footwell , prior to that 18 months without trouble (car is a 2003 model). Tested the windscreen by pouring water on it , and water appeared to collect behind the pollen filter housing just above the vent which runs down to the footwell. Thought the rubber trim at the base was at fault , so sealed with a little 'aquarium silicon' and all seemed well. Come back to the car tonight and there's a pool of water again . All drain holes appear to be clear . I'm sure it's rainwater and not coolant - all levels seem OK .I've googled plenty but cannot find anything relating to the drivers side.

Any help appreciated

Hi andymacc

I agree with your searching, that the C3 is not know for leaks, other than the pluriel, which is synonymous with leaking. So I am thinking you have a unique to your car problem, maybe thanks to a previous owner. You are on the right track with a bucket of water, but having two people helps (one to pour water and the other to observe and feel while twisting into an odd shape to reach the point of water entry).

The coolant colour should be bright red, to there is no mistaking rainwater for coolant (just soak some up in a tissue).

Wash wipe water can be any colour, from yellow to blue, but it should have a colour to it.

The condensate from the air con is clear, and just like water with nothing added, but you only get condensate while the air con is switched on and running.

Do let us know how you get on!
