Horn quit working? fuse good inside, and cruise works?
Suggest checking if 12 volts goes to horn wire at horn end when horn pressed from inside vehicle. A 12 Volt probe {google it} can be a cheap checking tool for this.
If 12v volts is switched when button is pressed {could be earth being switched if it is then place probe on constant 12 volts and negative lead on switched earth wire} then the horn itself is faulty.
If no voltage switched then horn relay needs to be checked. check if voltage at horn relay coil contact when button pressed.
if yes then relay may be faulty. if no then horn switch could be faulty.
you can check switched voltage also at horn relay switched contact when relay plugged in. To see if relay is doing what it is meant to do
Every where I look? Explorers 07 and up don't have a horn relay anymore. only a fuse or something in the steering wheel connected with the airbag?
Also? how do I get to the horn wire with out tearing the left front fender off and wheel well?
check the wire at the relay that goes to the horn first and see if voltage is being switched to the wire that goes to the horn. If no voltage or earth wire being switched you may not need to go to the trouble of looking at the horn wire . The most common way on most vehicles would be to undo the plastic clips that hold the mud protection under the wheel arch there may be a plastic screw s that screws into the plastic clips. Undo and remove these screws and then pull out the clips . Screws could be straight into the metal depends on the vehicle maker. I removed a mud protector and had to loosen a fender on a commodore VN to get access and replaced a power aerial.
the horn relay will be under the cars bonnet in a plastic box compartment for special fuses and relays. May be right behind the battery depends on the vehicle. the cover of this box may also have a map to what relay does what .
I looked in the manual in glovebox and nothing for horn? The plastic box shows nothing for horn either? Im stumped. I do appreciated your time and answers on this!
Mark with further research - there may not be a discrete horn relay it is most likely in the csm module and your csm anti theft module may have a fault. http://www.ford-trucks.com/forums/530752...
