The in dash display should automatically vary its brightness based on the amount of light in the cabin - the sensor in the clock module should control it... I was wondering if people knew how to test it and how easy it is to replace.
Now this gets odder. The display varies its brightness during the day no problem at all BUT when I turn the lights on it jumps to high brightness... unless I turn the dash lights right down in which case it dims down and if I shine a light onto the sensor it brightens up again.... so I think its time to take the clock apart and look for light leaking onto the light sensor
ian - I can't see mine either. Could be the bulbs. THought this was pure LED, but apparently there are bulbs in there - if you shine a torch on the display, and you can make out the display figures, then it is just the bulbs.
Must admit I've not got round to trying this myself yet!
