Iam an ASE Certified mechanic and i had the same problem with my 99 century and i wasnt able to drive at night. After hours of testing wires we came to the problem. Its the turn signal switch assembly which is tied into the hazard switch on top of the steering column. Its all one piece with a 3 foot long wiring harness attached to it running down the bottom of the steering column and going underneath the dash. The least expensive place i found the part and had it in stock was my local Auto Zone and still the part was $200.00.

SOURCE: low beams on my Buick Century 2000 Quit working.

you have to remove the steering wheel and get inside the steering column

SOURCE: Low beams stopped working

There are two fuses...one 15amp that is for the daylight running resistor, the second one is a 20amp which is for the headlights...both of them are IP(Inside Panel), not UP(Underhood Panel) which means both are inside the vehicle. The dimmer switch receives power from the 20amp which by switching it causes the power to go to the high or low beam. That being the case, it would appear that your dimmer switch which is under the dash, located on left lower side of steering column, would be the likely suspect.

SOURCE: no power at fuse block for low beam head light

hello, the left and right headlight fuses are powered by the same circuit. the circuit is bus bar inside the fuse block. if you are 100 percent sure the fuse is dead, then the only possiblitie is a bad fuse block
