I assume it didn't work before you changed the bulb either. You'll have to check for voltage at the bulb socket when the low beam headlights are turned on. If there is none you'll have to trace the wire back to where it splits from the right low beam headlight. If there is voltage there you have a problem with the new bulb.

Headlights wont work on dim, only bright


Check your head light bulbs, your truck has the dual filiment headlight bulbs one per side which does both high beam and low beam, 9007 bulbs.
If the low beam filiments are burned out only the high beam will work.
Also look into finding out if the headlight switch is gone bad.
The headlight module and or drl module maybe defective.

One low beam head lights will not work, high beam works though


check for a damaged wire for the low beam. Also wouldn't hurt to check the ground wire as the high beam will try and ground through the low beam but not visa verse

One of my turn signals wont work, both my headlights only work on highbeams


replace the high beam switch which causes this problem. Also clean the terminals for the directional light bulb. That will cause a negative continuity to the bulb

The low beams on my 2006 buick lacrosse wont work the bulbs and fuses have been replaced but they still wont work


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.

Low beam not work !!


replace the headlight bulbs. Usually when the bulbs blow out the low beam blows out first, but the high beams still work. If you want and need both low and high beams to work then replace the headlight bulbs with brand new ones and I garauntee that both low and high beams will work
