I started the car up last night and the centre console clock wouldn;t display. Could a fuse have blown or is it something else that has gone.
Have you made sure the knurled knob, next to the headlight switch is not set to it's lowest dimming level?
Try giving the plastic above the clock a firm bang with your hand. It may sound ridiculous, but my clock display went a few years ago, one quick thump from a frustrated and short tempered individual later and it came back and hasn't gone away since. Obviously this could signify a loose connection, but I'm all for quick and easy fixes!!
Other than that the LED's behind could have failed and will need replacing.
instead of resorting to the above
shine a light on the unit with a torch or similar to see if the backlight has just failed
also check fuses etc - check fuse diagram in user manual or top of elec forum
