Random 'honk' /Door unlock/lock

[802]

Recently i have noticed my doors unlocking repeaditly and occasionaly locking while driving. My horn more often then not will also honk shortly after starting the vehicle up. Both of these problems are recent and i believe them to be connected. Has anyone else experienced similar problems? 2003 grand am gt

Check the electrical connections at the BCM, body control module, for poor contact/corrosion.

The left rear door lock mechanism happened to be stuck, and after spraying some wd40 the lock feature returned, the 'ghost' unlocking stopped and i havent heard a horn!
