1996 Honda Civic Lx 4 Door Speedometer Only Works Sometimes Gas Gauge Doesn T

I have a 1996 honda civic LX 4 door and the speedometer only works sometimes, the gas gauge doesn't work, and he odometer stopped working at 157,000 miles, none of the windows roll down, and some of the lights for the radio work and the volume control is touchy. Is this an electrical problem and how would I go about fixing this?
Thanks
