I had the exact same problem on one of our 97 Lesabres. It was about 2 years before I got around to doing something about it. I ended up adjusting the back, left side, door latch bolt so that the door pulled in tighter when it closed. This stopped the leak. I believe the water was leaking in at the top of the door by getting by the door seal. The water that runs off the roof kind of channels through there. When I adjusted the bolt latch, it pulled the seal closer and stopped the leak.
