Horn doesn't work

different cars different places. look on back of fuse cover it is either on inside fuse box, or under hood fuse box. if the fuse is ok! check the relay for the horn in under hood fuse box. if that is good.disconnect wire from horn, run a wire from battery positive to the horn it self, if it works now, it is the horn relay or button in car. Good-Day!

It could possibly be the relay itself or the horn. To test connect power straight to the horn, if it goes off then its the relay if not then its the horn.

Horn may be bad or switch on the steering wheel. The way to check either would be with a 12V light or meter.

the relay is probably under hood on driver side fuse panel.most dodge has a template on underside of cover

You can replace the horn. Check to see if the wires connected to the horn have power. Check with a test light. If power is present then the horns are bad.

check the fuse; the fuse box it's located under the dash on the left of the foot rest (drivers side)

The fuse must be in the main fuse box. The position and function of the fuses is normally marked on the inside of the fuse box cover and also in the owner's handbook. If you don't come right with these, work your way through the fuses looking for a blown one. To ease your search the horn fuse it should be around 30 amps. A small pair or pliers will help removing the fuses for inspection.

I am assuming you have checked the Fuse Box under the hood for the Horn Fuse and / or the Horn Relay and made sure both are good?

You can always try the steps outlined in this video to replace the horn pad. to see if this is your issue if you have exhausted all of your other resources.

Or You can try these steps to further diagnose your issues:

The horn relay on ZX2's is located underneath the dashboard on the drivers side. There are several relays located there - identify the horn relay by the "clicking" sound it makes when the horn is pressed. The likelyhood that you have a bad relay is minimal. Start by checking the horn fuse (the fuse box is located under the dash on the driver side). Next, check the relay. If the relay is making a clicking noise, it is probably OK. The next thing to check is the horn itself. it is located on the passenger side of the vehicle, up underneath the front bumber. Most instructions say to remove the bumber cover to get to the horn, but this is not neccesary. In my experience with Escort horn problems, the problem has been with the horn "switch", a wafer thin piece of plastic that lies between the steering wheel cover and the airbag assembly. Below are instructions for replacement of this switch - don't be intimidted by the procedure - it is not difficult.

You cannot buy a horn switch at a dealer - they tell you that the horn switch is part of the airbag assembly, which cost $450 plus. Understandably, Ford doesn't want people "messing around" with airbags. Go to a junk yard - you can eazily find and remove the horn switch from an Escort who's airbags have already deployed. I bought two of them for $5. Identify and remove the junkyard horn switch by reading step 7 below. This is an eazy fix if you follow these instructions. Should take about 10 minutes. I replaced my "stuck" 97 Escort horn switch as follows...
1) Disconnect negative battery cable, wait for at least 1/2 hour for residual power discharge before proceeding to net step (IMPORTANT!). This will disable the airbag. Neglecting this step could cause serious injury or death!
2) Remove two 10mm bolts directly behind the steering wheel - one on left, one on right. These secure the airbag unit.
3) carefully lift the airbag unit out of the steering wheel.
4) remove two small star-screws at bottom of airbag unit using star end screw driver - the horn wires enter the airbag unit next to these screws
5) pry the airbag cover (this is the front part of the steering wheel cover with the horn picture on it) off of the plastic tabs of the airbag unit, on the left & right sides - should come off very eazily.
6) now you can lift the airbag cover up (there are three rivets that continue to hold the top portion of the cover in place)
7) the horn switch, which is covered by a thin layer of dark foam, is a very thin plastic pad with two wires coming out (same wires as step 4). You can see wafer thin copper strips inside the plastic. The switch is held in place by three small plastic tabs. Remove the switch and disconnect the wires at the red connector inside the steering wheel.
8) replace horn switch with junkyard switch
9) re-assembly is the reverse of the removal.
This procedure should apply to 97 through 2002 Escorts, including the ZX2. Hope this helps someone save some money.

Check in your owner's manual for the location of the horn relay. It will usually look like a small metal or plastic box that plugs into either the main fuse box or the high amp fuse box under the hood. If your horn fuse is good then most likely the horn relay needs replaced.

I do believe that your vehicle does have a fuse for the horn, if so, you should be able to locate the fuse, inside the car, on the driver's side, right under the dash. There should be a cover you can remove to access the fuses, and most manufacturers include the fuse information on the inside of this cover.

I hope this gets your horn going.
