Re: 1991 3dr - water leak under drivers door

Are you sure the water isn't coming from the inside of the door due to the membrane being "faulty"?
I'd take the door panel off just to check. Water that gets into the door (and it does) should exit the drain holes. However water can track down the internals and will find its way out of any breaks in the membrane then proceed to fill the footwells.
Good luck, it's not the weather for drying sodden footwells!
