I have the same problem. We just had the sweeper seal replaced on one of our slides and only part of the top portion will roll out when the slide goes out. The side sweepers roll in and out just fine. I remember reading on a forum somewhere about using a kind of traction tape to help the seal roll smoothly and completely. For the life of me I can't find that post again now that I need the info. Anybody know what it is I'm talking about? I think it would solve both turkey22 and my problems.
