Great thanks for thatAssuming all other lights are working- most often both bulbs blown. Quite easy to change:
4x Hex screws under front of brown dash panel. Remove screws and GENTLY lift at the front and remove.
The two gold coloured Phillips screws at the base of the BIF (clock unit)
Lift out, unclip and remove.
You can now simply replace the bulbs.
NOTE: when retightening the hex screws only tighten them very slightly. It’s VERY easy to overtighten and crack the panel!
