98 grand am se..erratic gages and warning lights
 

I recently bought a 98 Grand Am SE 2.4 Twin cam. I started having trouble with the temperature and tach gage working erratically. If the gages stop working then the warning lights stay on while it is running. The car always starts and runs good and all lights and accessories work. When this happens I can hear a clicking under the dash. I have checked the fuses and took the ground cable off the battery and engine block and cleaned them..still acting up though. I need suggestions of what else I need to check. Thanks.
