The dimmer switch relay for a 2000 Buick Century is Located under dash right side of the fuse box.

the multi-funtion switch needs replaced(dimmer)

Sounds like a bad dimmer switch.

u need to replace the multi-funcition switch in the steering colum...hope it helps

no low beams on my 1999 buick century change headlight bulbs and still no low beams

I assume you have changed the bulb?

Go through all your fuses, Dim lights run on a separate fuse.

When I try to use the high beams on my 2003 buick century they will not stay on when I let go of the lever and when I do let go of the lever sometimes my headlights will all go out. I just gave up on using the high beams at all
