Just wondering if my sunroof works normal. When I open it till it stops at fully open, I have to release the button and press again to get it to move the last 1/4" or so. Same with the tilt feature. As if the 2nd button push "locks" the sunroof into its final position. But I don't have to do this when closing the roof. Does yours work the same way? Is this maybe something that earlier models did? It's worked like this since I bought it, just wondering if there is something wrong?
