So while you need to sound your horn as sparingly as possible and only when you need to, you should never drive your car without it! But what if your Toyota Corolla&rsquo;s horn doesn&rsquo;t work for some reason?<\/p>\n\n\n\n<p><strong>If your Toyota Corolla&rsquo;s horn isn&rsquo;t working, it could be due to a blown fuse. The horn circuit has a dedicated fuse, which can blow due to electrical issues or overuse. To fix this, locate the fuse box, often found under the dashboard or in the engine compartment. Identify and replace the blown horn fuse, typically labeled in the fuse box diagram. Replacing a blown fuse is a simple and effective way to get your horn working again.<\/strong><\/p>\n\n\n\n<p>Another solution is to check and, if necessary, replace the horn relay. The relay is an electrical switch that controls the horn and can fail over time. Locate the horn relay in the fuse box and replace it with a new one. This is a straightforward fix that doesn&rsquo;t require specialized tools and can be done quickly, restoring the functionality of your horn.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"427\" src=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-1.jpg\" alt=\"Female hand pushing car horn on steering wheel\" class=\"wp-image-1122\" srcset=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-1.jpg 640w, https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-1-300x200.jpg 300w\" sizes=\"(max-width: 640px) 100vw, 640px\"><\/noscript><img loading=\"eager\" decoding=\"async\" width=\"640\" height=\"427\" src=\"data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%20640%20427'%3E%3Crect%20width='640'%20height='427'%20style='fill:%23e3e3e3'\/%3E%3C\/svg%3E\" alt=\"Female hand pushing car horn on steering wheel\" class=\"wp-image-1122 eager-load\" sizes=\"(max-width: 640px) 100vw, 640px\" data-pin-media=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-1.jpg\" id=\"mv-trellis-img-1\" data-src=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-1.jpg.webp\" data-srcset=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-1.jpg.webp 640w, https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-1-300x200.jpg.webp 300w\" data-svg=\"1\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>This article will talk about the things you need to do to figure out why your Toyota Corolla&rsquo;s horn sound is off or why it doesn&rsquo;t honk at all.

There may be a problem with the fuse, the horn relay, the horn connector, or the horn itself. After all, the horn sits in the front portion of your vehicle, exposing it to rain, light, and certain chemicals on the road.<\/p>\n\n\n\n<p>These things can corrode the ground or get into the inner parts of the horn and cause a short out in the coil, damaging the horn. It can also blow the fuse.<\/p>\n\n\n\n<p>There could also be a problem with the electronics in your steering wheel or the clock spring.<\/p>\n\n\n\n<p>Fixing or replacing the defective part would also fix your car horn. That means you&rsquo;ll need to check on these different components one by one. You need to know which parts are still working properly and which ones need repair or replacement.<\/p>\n\n\n\n<p>But before you start, familiarize yourself with the Toyota Corolla horn location and of all these other components involved in its function. You may want to take a look at your car&rsquo;s manual for this, as there are components located in the steering wheel, while some are under the hood of your vehicle.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Toyota Corolla Horn Location<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"427\" src=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-3.jpg\" alt=\"Female lifting car hood up and looking at engine bay\" class=\"wp-image-1124\" srcset=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-3.jpg 640w, https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-3-300x200.jpg 300w\" sizes=\"(max-width: 640px) 100vw, 640px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"427\" src=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-3.jpg.webp\" alt=\"Female lifting car hood up and looking at engine bay\" class=\"wp-image-1124 lazyload\" srcset=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-3.jpg.webp 640w, https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-3-300x200.jpg.webp 300w\" sizes=\"(max-width: 640px) 100vw, 640px\" data-pin-media=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-3.jpg\" id=\"mv-trellis-img-3\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>Your car horn is located at the front portion of your car. However, you&rsquo;ll need to pop your hood open and unscrew the plastic slat covering the space between the top of the grill and the radiator. Pry this cover open. In front of the radiator and behind the grill is a black disk with a wiring that hangs below it. This wire is plugged into a connector on the horn.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Toyota Corolla Horn Fuse<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"427\" src=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-4.jpg\" alt=\"Car fuses\" class=\"wp-image-1125\" srcset=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-4.jpg 640w, https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-4-300x200.jpg 300w\" sizes=\"(max-width: 640px) 100vw, 640px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"427\" src=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-4.jpg.webp\" alt=\"Car fuses\" class=\"wp-image-1125 lazyload\" srcset=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-4.jpg.webp 640w, https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-4-300x200.jpg.webp 300w\" sizes=\"(max-width: 640px) 100vw, 640px\" data-pin-media=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-4.jpg\" id=\"mv-trellis-img-4\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>Your car&rsquo;s horn works using electricity, and like other electrical parts, it has a dedicated fuse. Go to your car&rsquo;s fuse box and check the fuse for your car&rsquo;s horn. Take it out and see if it&rsquo;s blown.<\/p>\n\n\n\n<p>Modern vehicle fuses look like a fork, and if the wire between them is damaged or in poor shape, then the fuse is blown, and you may have just found the culprit. If this is the case, you may need to replace your fuse.<\/p>\n\n\n\n<p>A visual examination of your horn fuse isn&rsquo;t enough, though. If the wire inside your fuse looks good, it still doesn&rsquo;t mean there&rsquo;s nothing wrong with it. You&rsquo;ll have to check if there&rsquo;s voltage in there.<\/p>\n\n\n\n<p>Using a fused jumper, jump power directly to the horn at the front. Have someone honk your horn from the steering wheel. If your horn produces a clicking sound, that means the fuse and the horn relay are good, and it could be the horn itself that needs to be replaced.<\/p>\n\n\n\n<p>You can also check the fuse by swapping the current fuse with a spare fuse, which you can find in the lid if you haven&rsquo;t used it yet. Then, try to sound the horn or have someone else honk the horn for you from the driver&rsquo;s seat. If the horn still doesn&rsquo;t work, then the problem isn&rsquo;t the fuse.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Toyota Corolla Horn Relay<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"427\" src=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-5.jpg\" alt=\"Mechanic looking at car engine\" class=\"wp-image-1126\" srcset=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-5.jpg 640w, https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-5-300x200.jpg 300w\" sizes=\"(max-width: 640px) 100vw, 640px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"427\" src=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-5.jpg.webp\" alt=\"Mechanic looking at car engine\" class=\"wp-image-1126 lazyload\" srcset=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-5.jpg.webp 640w, https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-5-300x200.jpg.webp 300w\" sizes=\"(max-width: 640px) 100vw, 640px\" data-pin-media=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/06\/KMA-Bose-Microphone-Not-Working-5.jpg\" id=\"mv-trellis-img-5\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>The Toyota Corolla horn relay is also inside the fuse box. You can check the diagram on the lid to know precisely where the horn relay is.<\/p>\n\n\n\n<p>Check the horn relay by temporarily swapping it with another relay. If it works, then the horn relay is the problem. You may want to take your car to a professional mechanic to fix it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Check Your Steering Wheel<\/h3>\n\n\n\n<p>Your horn problem could also be related to the electronics in your steering wheel or the clock spring.

First, inspect the horn for any signs of corrosion, especially around the screw or bolt. Corrosion could result in poor ground connection and could keep your horn from functioning. Clean the area if you see traces of rust, then sound the horn after.<\/p>\n\n\n\n<p>If it still doesn&rsquo;t work, try the fused jumper trick, which we&rsquo;ve talked about earlier.<\/p>\n\n\n\n<p>Once you have pinpointed that the problem is the horn itself, a Toyota Corolla horn replacement is easy to do.<\/p>\n\n\n\n<p>You can also upgrade your car&rsquo;s horn even if it is still working but you are not satisfied with its volume. Just get a horn that sounds louder.
