My Mitsubhi L200 54 plate double cab is leaking rain water in the passenger foot well , i have removed wiper arms and grill and thoroughly washed out the channel below and drain hole but the problem still exists....can any one help please
many thanks

Is it coming through a grommet in the floorpan? , or possible a door seal?

Is it just the front carpet thats wet , as maybe leaking in the back ?

How much water we talking
