How to fix horn

Horn/cruise control stopped working. Replaced spiral clock started working again. Then when turning lt or rt abs would lock up. Had to remove fuse. Took to Dealership was told needed to replace steering angle sensor. Ordered it and had someone replace it. Now that we replaced steering angle sensor, horn and cruise no longer working again. Can u tell me what i need to do next? Both parts i bought were for my 2012 Xterra and were brand new.
