To access the fuse panel the glove box must be removed. It is removed by slipping the glove box strap off the hook and letting the door roll down off its hinges. To reinstall, position the glove box door at an 8 o’clock orientation, engage the hinge hook formations on the lower edge of the glove box door with the hinge pins on the lower edge of the instrument panel. Tilt the upper edge of the glove box door upward toward the instrument panel enough to reattach the glove box strap to the door. Rotate glove box door to closed position. Open and close to insure proper installation.
