2007 Saturn Aura car locks keep going up and down

Not saying this is a correct fix but found a bulletin for this concern. Subject: Protection Of Door Lock Switches During Window Tint Installation

Models: 2007 Saturn Aura Numerous door lock switches have been returned to the Warranty Parts Center for the complaint of "door lock inoperative" or "door locks cycling" where the root cause was determined to be moisture intrusion into the door lock switch. Further investigation indicated that many of the returned switches came from vehicles that had accessory window tinting installed.

Note: When using water on the inside of the window to apply the window tinting film to make the tint easier to manipulate be sure to protect the inside switches. Use care when squeeging out the water to remove air bubbles. If the switches are not properly protected during the squeegee process, excess water can enter and uprotected door lock switch causing the switch to become inoperative.
During the installation of window tinting film, Please protect the door lock and window switches to ensure that excess water from the installation process does not enter the switches. You might want to check the door switch for any intrusion of water. Could even be rain water soaking the switch when driving with the window open. Not sayin this is the fix but is a place to start.
