I'm sure this question must be answered somewhere on t'interweb but I'm not sure what to google for.
Two of the buttons on my dash (1997 300 Tdi Disco) are not illuminating. The heated windscreen button does not glow in the dark - although the light does come on to show that the button has been pressed in - and the rear-screen demister DOES glow in the dark but the orange light does not come on when I press the button.
Both buttons, when removed, have green and orange round things in them. I presume one of these round things has blown or broken - but I don't know what they are. Can I replace just the coloured round things? If so, what do I ask for and where do I buy them? And how do I get them out? If not, do I need to replace the whole button?
I'm sure this should be a simple job but I'm flummoxed.
