Question about 2006 Buick Rainier
Possible relay fault,also a burnt dimmer switch will cause this symptom

Very common problem, there is a re-call on this issue also. Turn your lights on, switch #43 Relay with #46 Relay (same relay, one is for Low beams, other is for fan. When you make the switch, you will have low beam lights again, get a new relay AND keep a spare in your glovebox, because there is no permanent fix yet on the re-call.
