Has anyone changed the liner in the door seal? I can't find any videos on it or instructions. I have the new liner but I'm wondering if it's an easy job or something I need to take to the dealer? Doesn't look like it's glued, but I don't know for sure. 2006 Aston Martin Vantage V8.

 

If you're talking about the seal that the window seals against there is a YT video of how to remove the upper chrome trim that includes removing the seal.

 

Are you talking about the rubber perimeter door seal? The one that your backside rubs when getting into the car?
I'm thinking of replacing that site seal in the near future. It's not leaking or causing any noise, it just looks bad when I climb into the seat
