Horn Relay is failing (switch is closing) perhaps due to cold weather. Take relay out and test in freezer to see if switch closes. Or, there is a short somewhere in the circuitry - especially look at the steering wheel horn switch, as that assembly moves and could have been chaffed.

It could be the horn relay which is typically located in the fuse box. It could also possibly be a defective horn switch which can be checked at the proper relay pin location. You will need a service manual for the proper pin location. The wiring could be bad. Or it could just be the horn itself.
