    Where is the horn located on a 2007 Buick LaCrosse


    Horns on most late model GM cars are behind or below the headlight. Many of these cars have headlight that are very easy to remove. The are held in place with plastic slides.... you pull the slide or release (there are usually 2) and the headlight assembly will come out of the body. Then you can look for the horn.

    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.


    The relay under the hood may have gone out. We had the same problem on our 2007 Buick LaCrosse CX. The bulbs were fine, high beams worked, all turn signals and everything except the low beams turned on. Turns out the relay had gone bad.
