Peugeot 306 radio and centre panel back lighting!?

I think my Clarion radio casette has died, just as I am about to sell the car - doh! I've sourced a replacement from ebay and ordered appropriate 'keys' to remove the radio to replace unit. (About a week ago the digi display started showing gobbledigook and the on/off wouldnt work. It worked occasionally if you tapped the lcd display. Its stopped altogether now). The backlighters have all gone on the dials on the console below the radio too (temp/fan blower etc), which is a bummer when you are trying to work them while driving at night! My non-mechanic girlie brain is screaming 'fuses' at me!! Suggestions please!
