21 Limited Horn issue

[chaoticaffinity]

So twice now , almost a month a part, the horn started sounding nonstop. It took pulling the fuse and leaving the fuse out over night for it to reset. When the problem occurs you can see the drl s faintly flickering. Unlocking / locking the truck pr trying to toggle the panic button does not do anything. It does not respond to pressing the horn button on the wheel when the problem is occuring but the horn button works normally after draining it off so i dont think its shorting or a bad clockspring.Especially with it also hitting the drls at the same time. I have house cam video of the last time this occured and the horn just fires and the flight start to flicker . There is no one or anything in the truck when it does. Right now it is at the dealer for a diagnostic but I doubt they will find a fix with it being intermediate. I think it is prolly a bcm module or the horn relay. Anyone else seen this problem?

This same thing just happened to me this weekend. I pulled the fuse and now I'm debating next steps to take, hoping to not have to take it to the dealer. Did you ever find a cause/fix?

Hey there. I would like to take a closer look at your horn concerns on my end. To get things started, can you please send over a message with your VIN and the name/location of the Ford dealer you are working with?

Might put a battery in it.

It did not reoccur for the dealer and has not occured again yet, It could have been battery i suppose. But i didnt check it at the time . I also have read that keeping the inside fan set to 5 or above forces charging of the battery i have kept it set to that since.
