Hi guys.. I have had a slight leak coming in through the top of the drivers window on my coupe.. Until now it has only been a slight trickle, and then only when hosed during washing. However, I was driving in heavy ish rain the other day, and was getting drips coming in. I seems to be from where the window meets the seal at the top. Do I have to replace the door seal, or can I carry out some sort of adjustment or modification to it to keep dry? Any advice is warmly welcome.
