Water in the footwell
Water in the driver's footwell might be from above the screen or the A pillar or the screen itself, but many of us have found either blocked drain pipes (through the transmission tunnel) and/or a hole in the scuttle where the blower motor mounts. Usually the front 2 bolts. Mine had both. There is a design flaw in the blower motor area- there is no drain - large amounts of water drain via the 4 drains in the box itself but a small amount sits around the mount bolt and rusts happily away until 20 years later when we get wet feet! There are other drains in the scuttle you should check. Put a funnel with a vinyl tube down each drain and pour water in one at a time. You may even feel it blocked by squeezing each rubber drain tube from the underside of the scuttle. Fixing a hole causing a leak was why I took out my dash and box.
