How to Replace the Horn on a Mazda 5by Marlo Peterson
When a stock horn in your Mazda 5 dies or malfunctions, it's important to replace it as soon as possible. Not only does a working horn warn others of your presence to avoid potential accidents, but also the car will not pass state inspections without a working horn. You can cheaply purchase replacement horns from used parts dealers or a junkyard. Installation requires unplugging the old horn and then plugging in the replacement horn.
Purchase a replacement car horn. Since this is a routine repair, you'd be best served to shop around for the cheapest part.
Turn off the engine. Open the hood of your Mazda, stabilizing it with the hood prop.
Locate the stock horn at the front near the grille. It is a circular part that looks a lot like a school bell.
Disconnect the negative cable from its battery terminal by loosening the screws holding it in place. This must be done before electrical work takes place. Unbolt the horn from its mount with a socket wrench. Put aside the bolts so you can use them for the new horn.
Unplug the set of wires that is inserted in your old horn's socket. Pull the old horn from the vehicle and set it aside.
Place the new horn onto the area where the previous horn was mounted and secure it in place with the bolts you removed from the stock horn. Plug the set of wires into the socket of the replacement horn.
Reconnect the cable to the negative battery terminal and close the hood of the car.
