When I try to close the sunroof by pushing the sunroof button forward past the detent (i.e. auto-close all the way), the sunroof will only close partially, and then open all the way again. This happens with the roof in any partially openned/closed position.

To get it to close all the way, I have to hold the button forward.

I read the manual and can't find anything about this. Does it sound broken, or is there something else going on that I am unaware of? Thanks in advance!

my sunroof closes automatically, but when i auto open it, it stops in the middle and i have to push the button again. it refuses to auto open all the way. from time to time it also decides to open all the way, mood swings?

dealer says they have to remove the headliner etc...so i didnt bother...
