Here is the procedure for re-initializing the power sliding door. Usually, the problem manifests itself during an aborted open or close, which throws the logic control module off. I have used this procedure myself several times to fix a ‘dead’ door. It should work on the Venture and Silhouette as well, although I cannot guarantee.
The reference to the Diagnostic Modes permits the technician to discover what caused the door to stop working and identify any failed parts (motor, sensors, module etc). I DO NOT have the diagnostic code information.
