Dashboard electrics gone?

Hi, i have a peugeot 306 1.9 diesel (S Reg). The rear demister, radio, hazard, fuel gage, speedo, rev counter are all not working.
I've checked the fuses and the relay but all seems to be ok.
Does anybody know what else this could be? With it being an older car, i don't want to spend to much getting it fixed.

Thanks
