I agree with Steve about checking the connections for the wires...
Look at the back of the panel and follow the wires coming out - follow each to it's connector and make sure they are in tight in the connector, the connectors are secure, and the wires aren't kinked or crimped under something. I believe the clock has 4 wires that are red/brown/green/black.
The clock isn't fused separately so that shouldn't be it. I believe the 2 instrument panel lights are on the same switched power 10A fuse...
