We usually have a decent long spell of nice weather in the fall and spring and I really enjoy using the pano roof so to worry that it could freeze up at any time is frustrating. My last freeze up happened on a nice sunny day but weather the next day was to be rainy. It was 4pm on a weekday when it happened and by sheer luck one of the dealers in town said if I rush over he could try to fix. They lubed it up and it finally worked. But I don't like worrying about things like this happening again.
