I want to add fog lights to my Lacrosse, I changed out the headlight switch and added the fog lights to the front fascia and I already had the fog light fuse in the vehicle fuse box under the hood. I just need to find the location of the harness located somewhere on the chassis.
The Easiest Way is to Get the Wiring Harness Diagram with the Colors and Verify that you plugged the Fog Lights into the Correct Harness. I once had a FORD that had a Fuse BOX that had a FOG LIGHT and No Power to that Fuse.
Make sure you test the Fuse at the Box and then Trace the wires and if the Switch was wired at the Factory, you should be all set
SOURCE: headlight fuse location
Headlights do not have fuses. They have circuit breakers (thermal cutoffs) ususally in the headlight switch. Headlight circuits aren't fused because once the fuse blows, you're out of luck. At least with a self-resetting breaker, when the circuit cools off, you again have light.
SOURCE: fuse box location
The fuse box or panel, is located under the dash on the far left, next to the parking brake release handle. Looking in this area, you will notic a small black plastic panel. Remove this panel and you will see the fuses.
There is a second fuse panel under the hood, up against the firewall. Remove the large black plastic panel and you will find a row of relays, and a number of large type fuses.

If you have power to the socket, then it's your bulbs that are the problem. Or a bad ground wire.
SOURCE: cannot locate the battery under the hood
The battery in my 2007 Lucerne is under the rear seat. Just pull up hard on the fornt of the rear seat bottom.

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.
