My 2002
MCS has an ongoing leak at the passenger door frame.
As far as I can make out, water is somehow getting to the middle section of the door seal (the pinchweld section) and finding its way into the passenger footwell.
I have taken the carpets out and can see where the water is coming from (inside of door seal at bottom of door frame).
I haven't had a chance to check how the water gets to the inside side of the door seal.
Here's the thread that I contributed to:
