1997 Plymouth Neon location of water temp and cooling fan s

I have been unable to locate the water temp and cooling fan sending switches on my 2.0 16 ohv engine. The temp guage and gas guage both kick back to zero after a few seconds of ignition on. Also the electric cooling fan runs continualy, however it does not start running untill the car has been started, it does not come on if the ignition is on but car not started.
