Put a voltage(12V dc) across the coil terminals and see if it clicks. At the same time put a test light (battery operated) across the switched terminals and see if the light lights up. If if does, the relay is good. If it clicks and the light doesn't light up, the contacts are band. If it doesn't click, the coil is bad.
OR GO to any auto parts store, buy a new relay( about $2.00) and plug it in.

2001 Saturn constant horn blowing?
Typically, that problem would only be caused by a faulty horn relay or a damaged horn contact switch inside the steering column. A frayed wire that rubs on a metal part of the vehicle. Since the relay is the easiest part to test, remove the relay and replace it with a similar relay FOR TEST PURPOSES ONLY. If the horn works properly with a replacement relay, put the relay you used for testing back and purchase a new horn relay. If the test relay left the horn ON, you probably have a damaged horn contact switch, in which you will need to replace the faulty component.
