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.
is it in the rear spoiler? Thru the trunk, light socket is right below rear window
I think the light assembly screws out from the inside of the trunk.
Should have an access panel inside trunk
power = light green ground = black
Open the trunk, there should be some long and short screws with nuts on them right above your head. If you have a deep well socket (recommended), you just have to take the nuts off. Then slowly lower the trunk making sure the light assembly stays on the car. Take it off and you should have access to all the lights.
You must remove the entire tailight panel - remove trunk liner and the recessed nuts.
I believe that one is accessed thru the trunk; lift the carpet out of the way and you should be able to remove the assembly.
Trunk light switch is part of the trunk light socket assembly...
There is a switch by the trunk lid and sounds like it needs replacing.
Immidiately to the left of the steering wheel, below the traction control switch/twilight sentinel/interior light dimmer controls. Note that the trunk button can be disabled by a switch in the glove box or another switch in the trunk on the locking mechanism itself.
Hey Phill=the front ones can be gotten to from the rear of the light assy and on some of the cars you can get to the rear ones in the trunk. GoodluckJoe
Get inside the trunk and look up where the speakers are located. In the middle, there will be a plate held on by two screws. Remove the screws and plate and you will have access to the bulb.
