Q: Car horn going off in the middle of the night

asked by on

The car horn is going off in the middle of the night.

It is possible that horn button may be sensitive to the change in temperature and be making contact in the night when the outside temperature changes. I recommend seeking a certified mechanic, like one from YourMechanic, to come and test your vehicle for you to determine if the horn needs to be replaced.
