Do your front fog lights work?

when that happened on my 94 ls it was the switch i had to replace,i checked with 12v tester first if i had power at lights,then at switch,iknow on some cars,if the boots used a lot,the wires going to bootlid can break,do the basic testing first,if no power at switch more likely a fuse

Thank you for all suggestions got someone coming to have look at it later

All the wiring diagrams I have are for the US models and of course they don't require rear fogs and therefore there is nothing about them in the manual.

Can't see it being much mine was converted for UK use and consists of a switch and relay a good auto electrician should be able to sort it for you.
