If the horn on your 2005 Volvo S40 keeps honking, it may be due to a stuck horn relay, a faulty horn switch, or a short circuit in the wiring. Additionally, moisture or corrosion in the horn circuit can cause it to malfunction. Checking the fuse and inspecting the horn mechanism for any obstructions or damage can help identify the problem. If the issue persists, consulting a professional mechanic is advisable.
