I.q leakage

[Maddiescar]

some one please help my Toyota I.q  is leaking in the passenger footwell when it rains. Not the air con. Re-sealed the window still leaking. It seems to be making its way down middle of car behind electrics and coming down under gear box down left side into the foot well. There’s a little bit of water on each side when the water drains but no leaves in there. I can’t seem to find the drainage pipe and not entirely sure it’s that. I brought the car in summer so did not see any problems then. Must of been leaking for months coz it’s was like a small lake under the carpet. Only noticed it afew months ago. I am going mad that I can’t reach this problem and want to smash my car up lol.. please please help me as I’m a single mum on limited money. :-( appreciate any help thank you.
