both my rear side marker lights are out.... i'm thinking its because of a fuse... i've been checking the fuse box for blown fuses but i don't know which one it is... any ideas? thanks for the help guys.

 

Go under the hood and pull your tailight fuse out...10 fuse*...put in the spare and you should be good to go...had the same problem this week and i am set to go now...mine didnt even pop, so it took some time for me...good luck

 

If you forgot to mention that front side markers and bunch of other lights are not working as well - do what Max2000SE said. But if they ARE WORKING - then it could be just bulbs. I've already replaced both on mine.
