The door seal wasn't the issue. One of the plastic door hinge covers was loose enough to remove, and water entered the pillar where the hinge wasn't welded completely fast. I put duct tape around the area before the last rain, and nothing leaked in this time! I read all kinds of stuff on the internet about possible leak areas, but that was not among them. It was an easy fix, though! I'll remove the duct tape and seal it properly with some sealant later.
I recently got my court subpoena for the accident that I was in. A few days later, the perpetrator's OBITUARY is in the paper! I guess he chose death over jail...I figured that this would happen. 8^/
