remote lock horn

[1tramp]

I have a 2017 Silverado LTZ. Sometime when I lock my truck with the key fob, the horn does not blow. Sometimes the horn is very distorted. Other times, it blows like it is suppose to.  This started a couple of months ago. What can be the problem.

Someone reported that cleaning ground contacts brought back their horn, it honk when using their key fob. 

 

If anything try cleaning the two grounds under your radiator and see if this help.

Can you tell me where exactly the ground and what it looks like? Not that mechanically inclined.  The horn always works when I press on the steering wheel. Thanks.
