i have a 2005 buick century and my head lights shut off only when i turn on my brights i checked the fuses but nuthings rong

If the fuse is still ok, then check the High Beam Relay, it may have failed causing them to not work. On alot of GM vehicles when you switch from low beams to high beams it shuts off the low beams and only has the high beams on.

Most likely the multi-function switch at the steering column. Rock Auto has them http://www.rockauto.com/?a=G-partdescribe2

Oh and I read your two reviews about the Buick Century. Which is it? A piece of crap or a great car? What kind of drugs you on kid? And that haircut went out in the eighties.
