My tab was 1/2 broken and then stayed put when I attempted to close the sunroof. Of course, since the shade wasn't moving forward, the sunroof went 2/3 closed and opened back up. As soon as I wiggled the shade out in the sunroof area, the sunroof closed properly.
I ended up removing the tab that auto pulls the shade so that I won't have the issue again. I think that the CA sun and heat ate up the plastic shade 'pull' and made it brittle.
Anyone have an extra grey sunroof shade 'handle/pull'??
