89 Horn Question
 

I need help on this I have a new Battery for the car but when I blow the horn you here a click no horn do I need a new one or a fuse or something:confused:

Use a volt meter & check the horn for voltage at the horn when you try to blow it. If you got voltage to the horn, then the horns is bad or has lost it's ground.

If you don't have voltage, check at the horn relay to see if there is voltage to the relay. It should be live at all times, or at least when the ignition is on in some cars.

When the relay is energized by blowing the horn, their should be voltage coming out of the relay to the horns.

If you got voltage to the relay, but no voltage from the relay when the relay is energized, then the relay is bad.

If you don't have any voltage to the relay, then look for fuse/wiring problem.

The relay is what you hear clicking, so you know you got voltage from the horn switch to the relay. This is just to operate the relay, not to supply voltage to battery.
