have u checked the relay on the horn maybe u have a bad relay
might be a fuse, check the fuse box in the drivers footwell
The cigarette lighter (I'm assuming that's what you meant) is on a separate fuse than the horn. Check that fuse, if the fuse is fine then your most likely culpret is the actual horn switch in the steering wheel.
Bad horn? Bad relay? Bad horn switch?
First thing to check is the fuse. If the fuse is good check the relay. If that is good check wiring. Can also be the horn switch or the horn itself.
Check the fuse, and all connections to the horn. If you find nothing wrong, then apply 12 volts directly to the horn. If it blows the horn is good, and the horn switch may be bad. If it does not blow, visit your local salvage yard for a used horn. dont think the fuse in the fuse panel is the only one for the horn... in the relay center under the hood there is a horn fuse as well, that was where mine was blown. good luck
The horn doesn't work
The horn doesn't work
I think the fuse is not good
I JUST had and fixed the same problem on my 2000 Jeep Cherokee. The fuse is blown, in the fuse box on the passenger side. I believe it is the 15 amp fuse #20 or #21. good luck!

My guess would be the horn or horn relay or connections between the them is at fault. The click you hear would be the horn relay trying to work, that tells me the fuse and horn button is in working order. Unplug the wire at the horn and attach a test light to the wire. Operate the horn button and see if the light lights or not. If the light lights up the horn is at fault. If the light doesn't light up and you still hear the click I would replace the horn relay.
Check the other fuses. Mine did the same thing and it was the Horn fuse that had blown. The bass power is on a separate circuit.
You could have shorted the stereo out, if so there is no way to check that. You might have to get a new head unit. Two wires have to have power in order for the stereo to power on: the 12 - volt constant (this gives power to the stereo even when the key is off for clock and setting memories) and the 12 - volt switchable (which tells the stereo the car is on and powers up the stereo). Remove the stereo plug from the back of the stereo - if two of the wires in the plug have power when the key is in the on-position (use a test light grounded to something metal) then the stereo is bad. If only one wire has power, you have a bad fuse or bad wire. If the constant wire is bad, simply jump a new wire to a constant fuse on the block such as the horn fuse (or run it straight to the battery and use an inline fuse). If the switchable wire is bad, tap into a wire at the fuse block that switches off with the ignition.
It could be the horn relay, a defective fuse or a shorted wiring. Need to check the wiring first, then the fuse and lastly the horn relay.
