Is your horn on your 2014-19 Silverado or Sierra continuously blowing, even with key out of the ignition? If so, in this video we explain how to fix this issue quickly and easily for good.

This issue is commonly caused by a bad relay located on the circuit board of 2014-19 GM trucks. The easiest way to solve this issue is to purchase a new Engine Wiring Harness Junction Block from your local Chevy or GMC dealer. The part number you will need to reference is GM 84303175.

This is an extremely easy fix for a very annoying issue. The unfortunate thing about this is that the Engine Wiring Harness Junction Block (GM Part Number: 84303175) costs approximately $260.00 at the dealership. So, this extremely easy fix is also an extremely expensive fix. However, if you follow the steps in this video, you can have your truck back to normal in no time at all.
