Some Subaru Outback owners report experiencing issues with their horn not functioning, which can be attributed to several potential causes such as a blown fuse, bad relay, faulty horn, corroded connectors, broken wires, or a malfunctioning horn button. Additionally, some owners have identified the clock spring as a possible culprit, as it connects the steering wheel's electrical systems to the vehicle's wiring harness. Even if other steering wheel functions, like cruise control, are operational, the clock spring may still be responsible for the horn issue. Furthermore, if the horn activates from the Panic Button but not from the steering wheel, this may indicate a problem with the clock spring. Before opting for a clock spring replacement, it is advisable to check for loose connections or wiring issues by inspecting the horn connection after removing the steering wheel.
