The fuse box for 2004 Suzuki Vitara is located on drivers side just above and to the left of the brake peddle. You have to get on your back on the floor to see it. It houses the fuses for cigarette lighter, radio, tail lights and dash lights as well as others. They are labeled. Second fuse box is in engine compartment on passenger side...no idea what they control.
remove the top dash panel closest to the windshield, then remove mounting screws for dash module.
