Should have an access panel inside trunk
I think the light assembly screws out from the inside of the trunk.
The 1999 Buick LeSabre was a popular car for its time. The trunk release latch is located on the lower left hand side of the drivers seat.
The socket size for the trunk tail light on a 2001 Buick LeSabre is 7mm. Bulbs can be purchased at most local automotive repair stores.
If you can not remove fasteners on outside, you may need to cut a section out of the inside of trunk to get your hand by the bulbs.
The spare tire is under the carpet in the trunk
how do you pop the trunk from the inside on a 1992 buick park ave
If the 94 LeSabre trunk does not have a remote release, check the rear sear to see if the back is removable, to gain access to the trunk. If there is no access, then either a locksmith will need to pick the trunk or you will have to drill the trunk.

3.8 or 3800? 4.5 quarts with filter. About eight cases in the trunk.
