2007 Buick Lacrosse low beam headlights both went out at once. Doesn't appear to be the bulb. Also checked the fuses under the hood and those both appear OK too.

Check the fuse box under the hood, a lot of cars have fuses for the head lights. Should be marked on the cover of fuse box.

under the hood # 35

From Info I have looked at I believe under hood micro switch relay 35 is for low beam and 34 is for high beam. It also looks like you have a different fuse for each light. The relay are for both low beam or both high beams. each headlight has its own fuse. I believe #4 fuse under hood is for passenger side low beam. fuses 1-4 under hood are for the four headlights as I understand the info I have seen.

switch in stearing colom bad

Shannon, you did not state if you checked for voltage at the fuse location-or better yet at the bulb location-
If a connection at the relay that feeds power to the low beams has come loose, then the low beams will stay out. Suggest that you locate the headlight relay (in a box under the hood) and verify that it is operating. If an assistant can operate the headlights while you listen (and feel) for relay operation, then you can eliminate that as an issue. Next would be the output of the relay (contacts could be bad) - and if you cannot open the relay to verify good contacts, then purchase a replacement relay (possibly from a junkyard) and plug that in.

Remember, the relay supplies the power to the headlights.

check the fuse in fuse box for the headlights....

your low beam bulbs are bad they go for about 21.00 dollars for a pack of two

there is a relay in the fuse panel located under the hood its called the HDM RELAY # 34 .

There maybe a headlight relay under the hood, most are in a protective box. There may be a fuse also under the hood. Ck the fuse if there is one and tap the relays with you low beams set to be on. Good Luck, Ned
