No stupid questions Kristina. The problem is just dry grease in the mechanism. The fix is simple, pull the panel and squirt some penetrating oil on the door mechanism, work it a few times and then button it back up. You don't need a body shop for this. Any mechanic should be able to accomplish this without new parts. Shop around for this so someone doesn't say "dumb broad eh, how much can I run up the bill?" Not that I think you are by any means, but you know what I mean. If you want to pull the panel yourself, it is easy.
