convertible top wont go down
i have a 2003 m3 and the convertible top wont go down, when you press the button, the top unlocks and goes up a little. but the top does not go down. when i put it down manually, it unlocks the same, and when i press the button in the back seat, the back part of the car where the top is stored will unlock and lock when i press the button. the only thing that does not work is the top it self, it is the only thing that does not move. i was told it was fluid. i was wondering how to fix it or what other problems it could be.
