We have a slight issue with the manual roof on my wife's 2004 beetle. When opening the roof you need to use more force than expected to get the roof locks engaged. I can do it OK by pushing down on it, but my wife struggles and cannot get the thing to lock.
I have lubricated the roof frame and the locks. It folds back and forth smoothly and there's no problem closing it. I can't see anything obvious. Any ideas?
