It is located in the fuse panel on the passenger side,right side of the dash next to the door,actually have to open the pass door to see the cover,once the cover is opened it is labeled as "RR FOG LP" 10 amp .On my 03 there is 6 rows of fuses/circuit breakers the fog fuse is the 3 row 2nd slot down (1 st slot in my 03 is empty ). Good luck
