Vauxhall tigra N 1995 speedometer faulty?

my tigra speedometer is not woking? i was on the daul carriageway and the speedometer just stoped working and 5min later when i was almost at work the power steering went off and the electric fault engine and the battery light came on after pulling over i switch off the engine and started it back up again the lights went off and the power steering came back on but the speedometer is still faulty i have taken a look at the 20amp fuse for the speedometer and it seems to be ok.
Any ideas on how to fit this problem?
thx
