How to repair horn

• 1. check the Horn honking, if the honking is not clear, low and weak, mostly poor contact.
• 2. repeatedly press the Horn of the switch, if the horn sometimes beep, sometimes do not beep, mostly press the switch inside the contact is not good.
• 3. turn the steering wheel left and right, if there is a large "hissing" friction sound, you can spray some grease to the relevant contact parts.
• 4. If the horn does not beep at all, it is likely that the fuse has been burned out, the relevant fuse should be checked. Or maybe there's something wrong with the horn's power cord. Find the speaker's power cord, the power cord wiring plug disassembly and assembly once, check whether the contact is bad.

The role of the relay

• Separate the original car horn wire from the horn directly, only to control the relay.
• The electrical appliances are closed to protect the horn circuit and the horn button from instant current impact.
