Sunroof sunshade doesn't close
Another small nit after dealing with my leaking windshield reservoir today. The sunshield in my sunroof is getting "stuck". When you do the "tilt" on the sunroof, the sunshade is supposed to retract about 4 inches or so. Mine no longer does this, it stays "closed" I have to forcibly pull the sunshade back and it takes a bit of effort. But from that point, I can easily move the sunshade back the rest of the way. Also when starting from the "tilt" position and opening the sunroof, the sunshade retracts no problem.
Any ideas what is getting stuck in those last 4" on the sunshade?
