Vauxhall frontera?

The instruments on my dash board crashed yesterday. No speedo, fuel guage, rev counter, temp. Have tried changing fuses. No joy. Prior to this, I have had an intermittant indicator problem. (cue for the joke...it is working, it isn't working, it is working....) Seriously, the indicators don't always work...especially in damp wet weather. Could the two problems be related? The car is 9 years old.
