Had this happen too, i just lifted the weather stripping up on the rear door and about a gallon came shooting out! Glad to see that was supposed to happen anyways. Where are the holes up top by the sun roof?
I believe those are to allow water that gets in through the window channels or anywhere else around the door to drain out the bottom of the doors. Since we don't have proper "rain gutters" on cars anymore.
As being the OP Glad this thread was somewhat beneficial to many of our esteem members here,also there is one drain hole on each corner of every door and also make sure that the tracks on the sunroof are properly greased,pics below. Z
Just pulled the weather stripping on the back doors and seems like half a gallon of water came gushing from each side. I'll have to check the sun roof drains this weekend.
It would see tat the problem is... If you just snake them the stuff that plugged the drain is still in there to make the next plug. Looked like Z had the door panel removed in his pic.
