Some of the air handling dampener motors are vacuum controlled and some have a small electric motor. If it's a vacuum controlled dampener, you probably have a vacuum leak, faulty vacuum diaphragm or disconnected vacuum line. If it's an electric dampener motor you have a bad connection, faulty feedback switch or faulty motor assembly.
