when cranking my car, I hear a tapping noise coming from the dashboard area. on 1999 Mitsubishi Diamante

sometimes I can stop the tapping noise by turning on the air conditioner and turning temp dial up or down till it stops. Sometimes it will eventually stop on its own. I don't want to do more damage--does anyone know what's going on.
