Thats the last thing you want to do. Pay like $100 for something that can easily be fixed. Just take a flathead screwdriver take out the vent above the clock. There you will see the screws for the navi box above the clock. Take those screws out and the whole box should come out with the clock attatched. Then there a very little screws holding the clock on. You take out those screws and you should see be able to take out the whole back of teh clock revealing the lights. The lights are like $20 each at the stealership but I got mine online for $3 ech.If the clock works during the day, then its not the fuse. I'd get it to a shop and have a professional check it out for you.
