Where are drain holes?

My drivers footwell carpet keeps getting wet even if I don't use the car. Somebody says the drain holes in bulk head are blocked but I don't know where they are.

Can anybody help?

Sounds like the Air con drain plugs are blocked . Mine did this during the Summer ( Ha Ha Ha HA ) with soaked drivers carpet for a bit. You need to get under the car and reach up into the gearbox tunnel and there should be 2 nozzles one on either side . There is a check valve in them and it gets blocked . The passenger side is harder to reach .Take them out of the nozzle and leave them out unless you are planning some wading. but keep em handy.

more like the drain pipes for the sun roof but i can be quite sure they wont be blocked it will be that thay have snapted off you need to remove the head lining to fix
