new to this forum, so if i say anything that is so obvious, be gentle.
i bought a 95 YJ a few months ago, same problem, always water in in drivers
floor pan. took a few weeks no narrow it down, inc. putting the wife in there while i hosed down the jeep. seems it was 3 places. the vent box outside, the overflow tube was filled with leafs, acorns and something that looked like a small pelt. flushed it out and cut off the bottom 3 inches. mainly where the flap was, keeps the tube open. 2nd was 4 holes drilled in the driver side, bottom, windshield hinge. a little RTV fixed that, and 3 was
i found a small gap in the windshield gasket, right at the bottom, dead center
where the water can run when the jeep is outside in the rain.
looks like that solved it, need to take her outside and let in rain, but it's pouring down here, don't want to get her wet, (ha)
anyway, good job on ripping the carpet out, 1st thing i did with mine.
plan on do the rhino thing in a few weeks, when it warms up a little here.:
