check gauge light cdmes on on 1992 Pontiac Bonneville

just started the check gauge light comes on but does not stay on... also noticed when it does the voltage gauge goes all the way down to the left....
also the windshield washer button does not work anymore.. does this mean the motor is bad?

ive noticed the "check gauges light"coming on when ANY of the gauges gets low including the gas gauge. try letting it run below 1/8 of a tank it'll come on
