Thanks for the video link - I'm sure that will be invaluable to many.
Had I seen that previously, I would also have realised that I dont actualy need the radio removal tools to get the climate control unit out - All that needs to be done is to remove the radio then push the CCU from behind ! This in turn would have made it clear that the bulb that illuminates the thumbwheel and LCD display has a simple provision for replacement once the unit is out.
Unfortuantely I'm no further forward ( infact I'm 100 steps behind!) in fixing the LCD display. Although the window is now lit, the digital temperature readout is blank - I assume the LCD has burnt out ?? Anyway, unless I can find some kind of electronics genius and just have that replaced, it would seem the only alternative is a new CCU @ £650 .... great !
Any thoughts ? Please !!
