The power sliding side door motor continues to run for up to three seconds after the door has fully closed or the customer may describe this as a grinding noise.
The power side door reverses prior to making contact with the pads and plungers.
Visually inspect the upper/lower roller tracks for foam and/or debris.
Manually operate the door applying downward pressure on the handle and see if the lower bracket contacts the primary seal. If yes, loosen and rotate the lower roller bracket to increase the clearance between the top of the primary seal and the bottom of the roller bracket. Inspect and adjust the front and rear door latches, strikers and door wedge as needed.
The power sliding side door reverses.
The power sliding side door starts to close then reopens.
The power sliding door reverses after making contact with the pads and plungers.
Visually inspect the pads and plungers for alignment and cleanliness. Also inspect the "B" pillar wiring for chaffing.
Visually inspect the pads and plunger for alignment and cleanliness. TAC has had cases where the wiring harness to the sliding door pad located on the "B" Pillar was chaffed at the base of the "B" pillar, inducing an intermittent reversal.
The warning chime sounds when the vehicle is placed into gear.
Verify that the power sliding door has not lost the learned open/closed position. With the Tech 2 updated with software version 25.009 or later, go into the Power Sliding Door menu and verify the "Open/Closed position learned" status. If either of the doors show "No", the door will have to be relearned. The power sliding door fuse will have to be removed and then restored. Open and close the power sliding doors twice with the overhead or "B" pillar switch to relearn the position. If the door reverses and/or stops prior to completing the two cycles, the procedure will need to be repeated.
The power sliding door will NOT automatically open when the outside handle is pulled.
The customer may comment that the door operates as designed when opened with an interior switch or key fob. Furthermore, the door will take off or open automatically once moved manually and the optical sensor detects movement. Remove the interior door panel, locate and replace the sliding door unlatch actuator (upper actuator).
Unable to tension the power sliding side door cables after replacement.
The power to the motor clutch assembly may have been connected prior to tensioning the cables.
Review SI procedures for Rear Side Door Actuator Cable Tension Adjustment.
U.S. dealers should also review the adjustment procedure on the GM Training website - www.gmtraining.com > TECHAssist > course 50250.20T1 (See Training Information below).
Ensure the cables remain overlapped 1-2 inches when the cables are properly routed and across the rollers.
Notice: Failure to properly tension the cables prior to operating the door will result in the motor clutch assembly being damaged.
