The park lamp relay contacts are stuck shut ,probably ! Do you know where the rear fuse box is ? Under the back seat . Check the relay first , if that's not the problem then the vehicles BCM maybe at fault .
The body control module (BCM) controls the park lamp relay through the park lamp relay control circuit. The BCM grounds the park lamp relay control circuit which energizes the PK LP relay.

I just did a 97 Regal yesterday and yes you are correct...the strip must be removed to gain access...depending on model you may have to remove the cushioning panel (piece of upholstery panel) on the inside of trunk lid...follow this video URL as it explains the removal better in video form than written..basically remove the 7 10mm nuts holding panel on, lower trunk lid a little and wiggle panel off, twist socket and remove to gain bulb access..install is reverse procedure ...Regal, Century and LeSabre are all same idea/setup Tail Light Change 1997 2005 Buick Century 2004 Buick Century Custom 3 1L V6

First replace the tail light bulbs. The tail light and brake lights are different filaments in the same bulb. it is very possible for the tail lights to go out while brake lights still work. And somtimes the tail lights can blow out together.
If you change the bulbs and still dont work then look for other problems.

open the rear hatch and on the left inside behind the tail light should be an cover. That will open to see the back of the light and then remove the bulb and replace with new

Both my remotes no longer work. I will be ordering new ones off Ebay and having my dealer program them. New ones from Buick are very pricey.

Remove cover from rear of trunk to access nuts. Remove tailight all 4 nuts. Pull tailight out. You will see the bulb sockets behind the tail light assembly. Turn counter clockwise to remove socket. Install same way.

Follow this link. Worked first time.
