Problem with headlights
 

HELP!!!
The headlights on my 2006 lacrosse will not come on. I have replaced the bulbs, no effect. They came on out of the blue, worked for a few months, then stoppped again. Bright’s work fine

Same thing only High beams
 

I have a 2008 Buick Lacrosse, at first the low beams would go off when i had some moisture but would come on after it was dry now for about 3 months only my high beams work. Thank God the lights are dim compare to new vehicles lights. I took it to a mechanic and it diagnisi it as either the fuse box needs replace on a light sensor and said it would be at least $400 for parts and time.
