Under the left side of the rear passenger compartment seat

You probably already have found it but here is a suggestion; The main fuse box is located to the left of the steering column, and there are other fuses behind the glove compartment. The relay/fuses for A/C fuel pump, etc are under the hood on the right hand side I believe.

On this website you find fuse box diagram and description for Buick LeSabre (2001) http://www.carknowledge.info/buick-lesabre-2000-2002-fuse-box-diagram

The fuse lay out is on the cover of the fuse box.If you don`t have the cover then you need to use the owners manual.There will be a label in the manual.Hope this helps.Good luck.

the fuse box may be under the hood or somewhere around the dash,as for the signal lights the blinker unit may be faulty & needs replacing you will find it under the dash on the drivers side it is a cylinder or a square box about 2" long with a connector plug on the top.....hope this helps....cheers

Hi J_livezey,
Your fuse box is located behind the right side of the dash,to the right of the glove box.Here is a diagram to better expalin.If you need anything else,let me know. Thanks,Chuck.

look at the other fuse box under the dash

Do you an Owner's Manual to look at. There are two fuse boxes on the 2000 Buick LeSabre. One is under the hood an the passenger-side at the front and the other is under the back seat. The Owners manual has fuse diagrams on pages 6-62 and 6-63 for the engine compartment box and pages 6-66 and 6-67 for the under seat box. Pictures and instructions are also included starting page 6-61.

Yes there is a fuse box it is under the back seat where the battery is...I have a 2000 buick lesabre and i have the owners manual to it.
