Dodge Caravan

We've got a 1990 Dodge Caravan and our horn does not work. It just stopped - It seemed it stopped after our rear - end was bumped by another vehicle one night. Anyway, where should we look to fix it? We've heard it can be the clockspring, but also the relay/fuse. In the interior fuse panel, there is no fuse marked horn.. would it even be there or marked differently. All look fine. I've heard there is a fuse panel under the hood as well, but I need more information on this, same for the relay. If you can help please explain the testing, I haven't done vehicle electrical work. Any ideas will help. Thanks.

 

There probably will not be a relay for the horn. Look at all fuses first. It will most likely be the fuse panel inside the vehicle.

I better route to take would just get a new horn or wire a new switch to the existing horn.

 

Any idea which fuse in particular, or what it would be labeled? Would it be one of the larger fuses that have plugs almost resembling outlets above that interior panel?

A horn from the wrecker would suffice as well?

 

Often, fuses are shared with other things so it might not be specifically labaled "Horn". I would pull all the fuses out and inspect them.

If the fuses are good, then it's most likely the horn switch or the horn itself.

A way to tell if it's the horn is to purchase a wire probe tester. These are pretty cheap at the autostore.

You will take this probe and stick it through the wire insulation going to the horn. While depressing the horn switch, observe the probe to see if the indicator light comes on. Check both wires. If it lights up while holding the horn down, it's a bad horn. If no light, then you have a electrical problem like the swich itself, or wiring.
