My 2003 Buick Century also did that today and I couldn't start my car. Apparently the key for the ignition has been damaged somehow and won't let the car start. Try using your extra key to see if that helps.
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.
I think the light assembly screws out from the inside of the trunk.
94 Buick Lesabre replaced battery and alternator and the alternator is not charging the battery. Battery light is on and off. Is this fusable link. If so where is it located
Cut the wire
Should have an access panel inside trunk
you can disconnect the negative cable at the battery for at least 30 seconds. if the problem is intermittent, the light will be out afterwards. if it comes right back on, seek a shop that does engine diag.
Disconnect the neg battery cabl;e for 30 seconds. If it comes back on, take it to auto zone and have the codes read for free.
Get a code read out from your engine computer and it will tell you what is wrong.
The price varies for a new tail light depending on where you shop for a 1998 Buick LeSabre. The new tail light can range from $33.00-$99.00.
