SOURCE: 99 CAVALIER HORN RELAY LOCATION
If your horn isn't working and it isn't the horn itself the next thing to check is the horn wire in the steering wheel under the air bag. The little clip breaks off in time and the horn wire pops out. To repair you can remove the wheel and replace the part but I usually grind in a new notch in the old plastic and re attach the wire and it will work again.
Test the horn itself first. Just remove the connection to the horn and attach 2 wires to a live battery and tough the 2 sides of the contacts on the horn. If it blows the horn is good. If not replace the horn before you go any further.

It doesn't actually have one this function is incorporated into the smart junction box.
The SJB monitors the multifunction switch position by sending multiple voltage reference signals to the multifunction switch. When the multifunction switch is in the LH or RH TURN positions, or the hazard lamp switch is pressed, that input signal is routed to ground.
When the SJB receives a request for a turn signal or the hazard lamps, the SJB supplies on/off voltage to the appropriate turn lamps.
The timed on/off cycle is determined by the SJB and is set to flash approximately 80 times per minute if both the front and rear turn lamps operate correctly. If an individual turn signal lamp is inoperative, the SJB fast flashes the remaining turn lamp approximately 160 times per minute to indicate to the driver of a bulb outage.
The SJB bulb outage is configurable and can be turned off for the rear lamps. This is to accommodate vehicles that have been upfitted with rear LED lamps in place of the traditional incandescent bulbs.

The horn is usually between the radiator and grill Assembly. The fuse is in fuse panel under the dash on the drivers side. Look at the lid and it shows the fuse placement and there use.

The horn relay is inside a fuse box under the hood (drivers side). There should be 5 relays. The horn will probably be mounted near the frame (under the engine).

On the side of your transmission will be a switch with several wires coming out of it. This is your reverse switch that turns on your reverse lights and most likely needs to be replaced
