I haven’t been able to use my horn for the past few weeks and I NEED it while driving in a summer destination area with tourists. I just realized though, the horn works only when the steering wheel is turned in either direction. I just reviewed the Haynes manual and don’t feel comfortable removing the air bag in the steering wheel to troubleshoot this problem let alone know what I would be looking for. Has anyone else fixed this problem and am I intimidated for nothing? 2015 Subaru Forester Touring
