After I accidentally set off the alarm when I opened the passenger door while it was armed. After that the horn stopped working. Any suggestions? I've taken the steering wheel apart to fix the stereo controls and that didn't seem to fix the horn. Also the trunk light comes on during the day, but not at night when it'* actually useful. :(
Thanks for the help in advance!

have you check for 12v at the horn? have you applied 12v directly to the horn?

the horn died in my 00 SSEi, I dont see why it couldn't in your 93

While the horn can die.. the 92-99 has a better position for not being filled with dirt and road debris. Check the fuses etc. There'* a good chance it blew.

Also check the relay for clicking.

I haven't cuz i don't quite know how. I have access to the tools that I need (voltmeter etc.) But just need to know where to put it and what setting to use.

Actually a test light is much easier in this case. One leg to the negative battery terminal (Black) and the other into the connector that goes to the horn. Press the button...does the test light turn on?

I'll check that out then. thanks

the relay isn't always reliable, just for listening to the clicking. My buddy'* GA'* horn went and he replaced the relay, even though it still clicked and after attempting everything else. The horn worked. So he pulled apart the old relay and the connection prongs had corrosion on them preventing a proper circuit.

Right...most of the time the terminals don't build up enough carbon to stop working..however it does happen.

Currently my horn is intermittent. I'm betting on a carboned up relay.

The clicking of the relay is the first step tyically in testing for power to the relay and heading first to a fuse or relay.

The relay is clicking when the horn is pressed, what does that mean? Should i check for carbon buildup?

First check the horn fuses. Then remove the relay and test for power to be relayed. If you have power..put the relay back in and test for power at the horns.
