Had some water leaking onto passenger floor. Found 1 leak which was coming from wire loom/grommet. Sealed up the A/C box pretty good everywhere we could reach. Windshield is not leaking. It only leaks when base of cowl is hit with water. The leak is coming from side of passenger footwell area. Can not see where. Doing some research and it seems that possibly where the floorpan and firewall meet is a source of leaks. A/C box trap was cleared out from debris- it was clogged. What next? Take off inner fender or the whole fender? We have to see in. Neighbor is helping me, he's pretty resourceful with cars.
