What's the 2012 Mazda 3 horn location?

The 2012 Mazda3 horn is mounted just behind the front bumper and within the grill of the car. It can be positioned under plastic covers near the hood latch. If Your horn doesn't work, there may be several different reasons. Some typical problems include a bad relay, a defective clock spring, a faulty horn switch in the steering wheel, or a broken wire/corroded ground. The first thing You want to find out is the fuse and the relay. You'll be able to locate them in the fuse panel within the engine bay. Then You should switch on to the horn and use the ohm meter to see if You're having power. The cost for a replacement horn will range from $25 - $50 depending on the brand and quality.
