wish I'd have read this this morning, I'd have taken photos!.....welllllll that was a right fart about! to change the bulbs you just need to remove the air vents, then the surrounds of said vents, the knob of the recirculation lever, then the heater control face (my cars an 08 so didn't mind the odd plastic clip snapping or marks from prying stuff apart with a screw driver!), the heater resistor is underneath the glovebox nearest the 'firewall' ,follow the multiple wires (x4 or 5 I think, will take photos tomorrow), remove the female connection part, then push in x1 plastic lever top n bottom of the resistor body n wiggle/prise that bitch out!...... to get at the resistor you'll need to contort yaself into the passenger footwell, have a torch n flat head screw driver n not be in hearing range of small children/delicate souls that don't like bad language ;-).....
