Does any one know what i can do with a leaking rear door seal on a 97 SSE? Is the seal avalible anywhere? Or is there a better way?

Where exactly is the leak (top, bottom)? Does it look like the seal has shrunk any?

if your door seal has shrunk you can expand it like many of us here have done

It'd be less time consuming to just replace the door seal, but if one rear seal is leaking, chances are good that the other door seals have shrunk also, so all of them may need to be replaced.

As for me, I chose to remove all 4 door seals and use clear silicone sealant to seal them instead. It took a while to do, but served its purpose.

Good luck.
