2001 Mits Mirage Gauges Wont Work

Ok, hopefully somebody can help.

2001 Mits Mirage, the gauges will work 50% of the time my car is on. I know its not a fuse, otherwise they would never work. The Fuel gauge, however, works 100% of the time.

Any ideas on how to fix this problem????

Intermittent electrical problems are tough to locate, much less correct. Try cleaning all the grounds you can find as well as all power connections. It might be as simple as that.
If that doesn't work, have a helper keep an eye on the guages while you wiggle wires under the dash. Any flickering will be a clue.
