The soft top on my 2001 Boxster will not go down. Actually the driver side goes down but the other side will not. As it starts to fold/retract one side does not move. My wife and I have tried a couple of times carefully. As I watched it go partially up and down before it starts to bind, I attempt to assist the pivot arm with no success. Before I take it in to the dealer, I was hoping someone could give me some suggestions on what I can do to correct this problem. I would like to put my hard top back on. Thank you!!!
