There are fuse panels located on the passenger side of the center console ('88-'89 models) and the drivers side of the center console ('90-'91 models).
On '88-'89 models one of the fuse panels can be accessed by a small door on the passenger side of the console. To access the other fuse panel the side cover of the center console must be removed.

In addition to the fuses under the console access panel, there is a second hidden 'Fuse Block' directly in front of the primary fuse panel, on the passenger side of the console.
You have to remove the console side panel to get to to the hidden fuse block.
Approx: 8 torx head screws hold it in place. There are seven relays in this panel. One of them is for the fog lights, another is for hi-low beam headlights. The relays are still available at auto parts stores or Buick dealer. GM part # 14100455
