So the alarm on the truck started going off by itself today. The key fob will not turn it off either. I pulled the horn fuse to make it stop and plugged it back in a few hours later. That worked for a while but then it started again. Anyone got any ideas on what might be happening? Thanks

 

Mine does the same thing.

 

Did you do anything to fix it or do you just live with it?

 

Have just lived with it.......didn't have any luck fixing it.........pull the fuse to the horn when it gets too bad

 

Mine was the dealer transport fuse unseated in the fuse block. Fuse is removed when they transport the truck and installed by the dealer as part of dealer prep.

Don't recollect which number it was. Took awhile till I understood what was causing it. Dealer said it was common and can occur long after installed.
