Not sure if this'll help but I have a '97 and it has twofuse boxes - one under the hood on the right side, and the second one is under the back seat.
My 1996 has one under the hood and another under the dash on the drivers side.

The fuse box for a 1998 Buick Park Avenue is located just below the dash near the driver's side floor board. It houses most of the essential fuses required to operate the vehicle.
