I have a 2007 Buick Lucerne. The fuse index does not indicate which fuses control/protect the taillamps. There are 3, 2 in the chassis fixture and one in the trunk fixture. ALL other lights work only the 3 passenger side tail lights are out. Which fuse is it? Wht didn't Buick put it in the manual? They have a different fuse for every other light of any kind.
