Please help my Wife

[-EnVus-]

My poor wife that i love soooooo much has a 2002 Mitsubishi Galant ES when its 30 degrees or colder the Horn goes off and wont shut off unless i disconnect the fuse. Its not the alarm just the Horn itself starts whaling nonstop. So for the past 5 years just when it gets cold enough outside like clock work my horn blows.

Any ideas ???

Yeah and its a bitch when its screaming at 3am and the doors are all froze shut

check all connections to and from the horn that blares away and clean all connections, and if possible put some dielectric grease in all the plugs/connections. like guy above, condensation is trapped somewhere and in winter it freezes and expands creating a everlasting circuit

Relay maybe
