For model year 1989 General Motors did not produce the Buick Park Avenue. The soonest production date to 1989 was the 1991 Park Avenue. The 1991 Park Avenue was offered in 3800 engine in supercharged or naturally aspirated. The part numbers for electronic control module (ECM) or "computer" will vary based on the exact engine for model year 1991s.

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.
