I had new headlight assembly installed and aligned today on my 2010, and now the fog lights dont come on. Is there something that they could've done to the headlights that would make the fog lights to go out or could it be a fuse or what? It's both of them so it's not the bulb?

 

Although unlikely, it is possible that both bulbs went out at once. Ensure they're okay. Black soot/film on the glass and/or a broken/thin/damaged filament means the bulb is bad.

Check the switch for them as well, rule out the obvious. If those check out fine then start checking fuses and relays. The fuse you want is located under the hood in the mass distribution box, number 31 rated at 15 amps, blue in color. Sometimes they're a rich, vivid, blue, other times there sort of a pastel type blue.

31 should be, according to the diagram, in the third row down (starting from the top), and the third fuse in, from left to right.

The relay will be 48B, on the lowest half of the box. Appears to be a mini relay compared to the others. There will be a row of relays at the bottom, farthest to the right, in what appears to be a block of two. 48B is the higher of the two. You can try swapping 48A and 48B to see what you get. 48A controls the fuel pump and fuel injectors, so if you stop getting fuel after swapping relays.... Well, safe to say it's no good anymore.

 

Ok thanks

 

check your ground wires, i replaced my headlights and had to reground my headlights, check ground points also

 

^ Eh? I assume you're referring to the bulbs and housings that were replaced. Did the connector come apart or something?

Incredibly strange that you'd have to go through that just for swapping that out.
