I don't have power on the fog light I got a new fuse but that didn't work what else can it be

 

Have you checked the bulbs to make sure they didn't go out. If not, I'd check w/ a multimeter that power is going to them. Check the relay also; may have gone out.

 

There is a number of things that could have gone wrong, check your grounds too. Relay should make a click when you turn it on/off. If not could be a bad switch but likes others said check to make sure there is voltage on the end of the fog, if not trace back to find the short.

 

Not familiar with the wiring harness if there's an extra relay somewhere. Was it the right fuse you replaced?
If all the obvious have been covered, then you'll have to check the bulbs.
Or
It need a new switch.

 

It was the relay guys thanks
