I have a 1997 jeep grand cherokee limited i was driving home and the instrument panel stated to flash on and off and there was a clicking from under the dash .. fist time to ever do that not sure what it is could it be a relay or the battery we jjust put a new bat and connector s on there thank you for your help

There is a relay that controls the lights and maybe your light switch is no good.when you put on the park or headlights,power is sent to a relay then to the dash via the dash dimmer switch,which is a load resistor.move the headlight switch around and see if has any effect.i would check the battery,fuse box under the hood,the light switch and the relay that is clicking under the dash.
