No front fog & only one rear fog light

Hi this has got the better of me
I've lost the front fog lights & also the auxiliary
12volt front socket & also one the near side rear
fog, the bulbs are ok (removed head lights & rear
cluster) the relays are ok (swapped with horn etc)
fuses are ok, removed radio and surround stripped
the switch down (thought it could have gone same
way as window switches) not so as I have operated
the switch contact by hand rear fog will light as it
should (off side only though) front will not light up

The only thing that has happened is I plugged a phone
charger in to the Aux front and the contacts came apart
this could have caused a short,

The fuse box lid says "front fog/aux" fuse are together

Any help would be greatly appreciated
