Ive a 2001 MK1 Leon and my Heating control back lights (HVAC Lights) wont come on. I dont have Climatronic just the 3 circular dials but none of the dials light up and its difficult to work them at night. Every other interior light is working fine eg the dash board, interior hazard warning light etc. Im aware that the bulb(s) in behind will need replaced and have seen that in a VW its a simple case of pulling off the middle dial and replacing the bulb (i thought the Leon would of been the same), but ive tried this on the Leon and the middle dial wont budge. Anyone any ideas as to how i get the plastic cover of off as ive tried to simply pull it but i dont wanna break it.
