If you are trying to remove just the plastic portion, there is screw inside at the top of each the four air ducts that need to be removed. I think the screws along the glove box need to be removed also.
The Buick Park Avenue Started In 1991
You have to remove the engine mount next to it, then remove the 4 bolts in the pulley
unbolt it
Pull the bulb...
You just remove it from where it is located. It is located under the dashboard on the driver side of the steering column mounted to a support bracket. Very easy to do.

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 diagnostic port on a 1991 Buick Park Avenue is located under the dashboard, near the steering column. It may be found above the brake pedal or to the left of the steering wheel. This port is typically a rectangular connector used for accessing the vehicle's onboard diagnostic system.
