BEHIND YOUR FUSE BOX, WHERE THE ACTUAL RELAYS SIT, THERES A GREEN RELAY WHICH IS PRONE TO BURN UP A BIT FROM TIME TO TIME.

THIS RELAY CONTROLS THE FAN, FOG LAMPS AND HEATER.

JUST UNDO THE TWO FUSE BOX SCREWS UNDER THE FUSE BOX PLASTIC COVER, PUSH THE BOX INTO THE FOOTWELL AND REPLACE THE RELAY. TEN MINUTE JOB.

HOPE THIS SOLVES THE PROBLEM.
