Take it this way, you're practically guaranteeing nothing will happen if you don't talk to her, especially if she's shy!
There's no end of threads (including my own (very old)) in here where the only answer is to talk to the subject of their problem. Don't worry about whether she likes you unless you have the courage to talk to her.
I understand 'how' to talk to her is your question. Ask her, for example, "have you seen Dukes of Hazzard?", then continue that, no matter how stupid you feel.
Good luck.
