My 3 year old corolla has recently been serviced. I asked the engineer to replace the dash lights (2) to illuminate the heater/ aircon etc. controls. I supplied the bulbs, previously bought from halfords. They charged me £20 for this. Two weeks later 1 of the bulbs has blown. I dont want to go back to the service place for them to charge me another £20. I dont think theyll do it for free as they didnt supply the bulbs. SO, my question is how do i get behind the dash to replace the bulb my self? Help please!!
