I just picked up my first explorer--02 EB and now find out the cd player doen't work (bought it at an auction). This is what happens-- When I press load the cd changer says 'full'; when I press ej it says 'no disc'; when I press the cd button it eventually says 'cd error'. Also, I can't push the cd door open to peer inside. Is this normal or could there be something jammed inside the player? Should I attempt to fix it or just shop for a replacement?
