As Jakedawg says. And I hate to say like so many others but get the factory manual, not Clymer,not Seloc. They are you only salvation sometimes, especially with the VRO and warning horns. I had the same issue for quite a while, drove me nuts. Finally disregarded the buzzer, just once, and blew my motor. So do as Jakedawg says and report back. Check your temperature sending wires. There is a diode in the harness that in combination with a bad wire will set that buzzer off if bad and it will keep going off til you turn the ignition off and restart. Look for some of my old post regarding the warning horn, system check ect. I know you dont have system check but you may see something in the post and replies that can help. Good luck.
