Hello do you have a volt meter to see if you are getting power on pin 86 and ground on pin 85 when the fog lamps are on?
If you turn on the fog lamps see if pin 85 is seeing a ground. If it isn't then the foglamps aren't being activated by the headlamp switch.
Sorry pin 85 is the ground side pin 86 is the power side.
