The windshield wipers and the horn are not working.
Hello. The first thing to check is all the fuses. If all the fuse are good, a scanner needs to be connected to car to check for code and data. Everything in the column and steering wheel goes through the steering column module. If this module fails there could be other issues you haven’t noticed yet. You will probably need the aid of a mechanic to connect a scanner and see if the steering column module has failed. They will be able to diagnose your electrical components and make any of the necessary repairs.
