Any help would be great

[yaris-one]

all the plugs are in order, i ripped out the whole carpet and seats and all, in fact im sitting in my driver seat, in my living room typing this right now...lol. it seems as though the water is comming from somewhere in the front and flowing into the back where it sits and soaks

and the lock doesnt seem as though it is going as far as normal.theres nothing stuck in the lever mechanism by the door handle, but i cant rele see by the actual lock due to it being bolted to the inside of the door, and the key doesnt work either
its not rele too much of a problem, considering the only place the car goes is in my driveway in the middle of nowhere and to work would just be nice to fix it soonish
