Scirocco Register

My indicator light on the dashboard seems to be intermittent. It hasn't been on since thursday. I checked the indicators were working themselves which they were and also I noticed last week that where I turn the blower dial etc they were lit up but now they aren't. All the other lights on the Dashboard (oil, battery, beam etc) work.

Any thoughts

broken wire, damaged pcb on the back of the clocks, bad earth, bulb blown
