This bulletin applies to 2009-2010 Ram 1500 pickups featuring the quad cab (4-door) design. One or both of the rear quad cab doors may not lock or unlock using door panel switches or the remote, but will lock and unlock manually.
The cause is an improperly installed wire harness that may be too close to the bell crank.
1. Remove the door trim panel.
2. Re-route the door lock wiring harness away from the bell crank mechanism to a 90-degree angle and reduce the slack in the wiring harness. Secure the harness with a zip tie to the routing tab.
3. Reinstall the trim panel and verify operation.
