Is250c convertible top won't open
 

Hello I have a question in regards my 2010 Is250c convertible top. I of course adjust the trunk compartment and make sure is locked in place , then I go to push the button and nothing !! Not a sound!! I'm about to take it to the Dealer but I want to see if anyone can help me before I do so... I'm in love with the car but I'm having buyers remorse..
