1993 Honda Accord SE 2dr. After many hours of investigating a driver's side water leak, I have identified the source. First steps were ensuring clear evaporator drain, sunroof drains etc .. then onto removing windshield cowling and front fender. The leak was coming through the sunroof drain tube knockout in an internal sheet metal panel above fuse panel. I had a helper hold a light while I hosed the area in specific locations. I post this hoping to help someone else in their water leak searching ... I was getting close to drill 1/2" drain holes on the floorboard. As per first picture, the sealant was intact but was porous and water could be seen soaking through.
