I find this subject pretty amazing ---- I HAVE THE EXACT SAME EXPERIENCE!
back right door --> check
after rain storm --> check
temperature --- WARM (90+ degrees)...live in Florida
probably 1.5 to 2 gallons of water in the door....slowly dripped out holes on bottom
this water must get in through some kind of bad seal/design around the window
the way I park, wind/rain blows from the back of the vehicle ---- I now back into parking space (see if this affects water in door next storm)
Questions:
1. did anybody have their seals checked/replaced AND did it stop the water from getting in the door?
2. cost?
3. I'm worried about rust inside the door --- anybody experience this problem?
4. Even if water drains (as apparently designed)....wouldn't this cause rust inside door?
