Sliding Door?

To help everyone out. Make sure the contact pad and plunger set in the each door jamb is clean. If not clean it with a non metallic scotch brite pad. As far as the motor operating after it closes. The door is not adjusted properly. Try pulling off the weatherstrip near the rear striker. Take an adjustable wrench put it on the flange and bend it out to the door a quarter of an inch a foot above and below the striker. Reinstall the weatherstrip, pull the sliding door fuses for 30 seconds. Operate both doors with the switches off and couple of times and then try a few times with the power switches. Hopefully this will put more tension on the door and relearn the position of the door. Check out the diagrams (Below). Let us know what happens and please upload pictures or videos of the problem.

No recalls, but two Tech bullitens, this one, and another one that has to do with the motor continuing to run after the door closes. That one requires a reprogram of the door control module.
General Power Sliding Side Door Diagnosis/Repair Procedures TECHNICAL SERVICE BULLETIN Reference Number(s): 07-08-64-007D, Â Date of Issue: Â July 21, 2008 Related Ref Number(s): 07-08-64-007, 07-08-64-007A, 07-08-64-007B, 07-08-64-007C, 07-08-64- 007D ARTICLE BEGINNING SERVICE INFORMATION CONDITION 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 (Overcinch). CAUSE Fig. 1: View Of Bent Roller Courtesy of GENERAL MOTORS CORP. 1. A center roller bracket may be bent or have loose rollers. Refer to the illustration above. 2. The power sliding side door may not have the latest programming. 3. The door is closing too quickly. It needs to see two detente signals 450 milliseconds apart. The latest program calibration for the PSD, in combination with the door to body adjustment and the proper seal flange adjustment at the rear latch, slows the sliding door into the latch, allowing the system to appropriately determine the secondary and primary latch position. This minimizes overcinching. CORRECTION 1. Remove and inspect the center roller bracket. If the rollers are loose to the bracket or bent, replace the bracket. 2. After replacing the center roller bracket, check for a properly tensioned door. Refer to Rear Side Door Actuator Cable Tension Adjustment. 3. Upload the new programming. Latest PSD Software calibration can be found on the Service Programming System (SPS) using "TIS2WEB". Input of the VIN will find the latest software Affected Model(s): 2005-2007 Buick Terraza; 2005-2009 Chevrolet Uplander (Includes Canada and Mexico); 2005-2009 Pontiac Montana SV6 (Includes Canada and Mexico); 2005- 2007 Saturn Relay Supercedes: This bulletin is being revised to update the model years.

calibration program to upload to the PSDM controllers in the vehicle. If the overcinching is still present, go to step 4. Fig. 2: Bending Primary Weatherstrip Flange Courtesy of GENERAL MOTORS CORP. Fig. 3: Locating Flange Adjustment Area Courtesy of GENERAL MOTORS CORP. 4. First, verify that the door is flush to the rear quarter panel or inwards 1 to 2 mm (0.039 to 0.078 in). Remove the primary weatherstrip. Using an adjustable wrench, bend the primary weatherstrip flange 1/8 inch outboard for a distance of 457 mm (18 in) above and below the striker. Refer to the illustration above. Adjust the flange above and below the rear striker. It may take several adjustments to get this correct. Once the door is operating with no overcinching and no binding, crimp the primary weatherstrip carrier together before reinstallation. Refer to the illustration above. CONDITION The power side door reverses prior to making contact with the pads and plungers. CAUSE Visually inspect the upper/lower roller tracks for foam and/or debris. CORRECTION 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. CONDITION The power sliding side door reverses. CAUSE Fig. 4: View Of Door Opening & Tracks Courtesy of GENERAL MOTORS CORP. 1. Inspect the door opening and tracks for obstructions. Refer to the illustration above. Fig. 5: View Of C-Pillar Striker Alignment Courtesy of GENERAL MOTORS CORP. 2. Inspect the C-Pillar striker alignment. Refer to the illustration above. Look for witness marks on the top and bottom of the latch. Turn the system off and close the door. Open the door slowly and look to see if the door jumps up, or falls off the striker. The striker should line upwith the center of the latch. Its purpose is to hold the door shut and adjust in or out, not up and down. Up or down adjustments should be made at the center roller bracket. Fig. 6: View Of Pad & Plunger Alignment Courtesy of GENERAL MOTORS CORP. 3. Inspect the pad and plunger alignment. Refer to the illustration above. Fig. 7: View Of Pin & Pocket Alignment Courtesy of GENERAL MOTORS CORP. 4. Inspect the pin and pocket alignment. Refer to the illustration above.

Fig. 20: View Of Hardware & Fasteners Courtesy of GENERAL MOTORS CORP. 4. Align hardware and seat all fasteners. Refer to the illustration above.CONDITION The power sliding door reverses after making contact with the pads and plungers. CAUSE Visually inspect the pads and plungers for alignment and cleanliness. Also inspect the "B" pillar wiring for chaffing. CORRECTION 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. CONDITION The warning chime sounds when the vehicle is placed into gear. CORRECTION 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. CONDITION The power sliding door will NOT automatically open when the outside handle is pulled. CORRECTION 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. This condition is caused by overcinching. The controller did not recognize the primary latch signal, therefore it ignores the handle switch input in the following cycle. Perform the overcinch corrections. CONDITION Unable to tension the power sliding side door cables after replacement. CAUSE The power to the motor clutch assembly may have been connected prior to tensioning the cables. CORRECTIONReview 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. U.S.A.

NOTE: Failure to properly tension the cables prior to operating the door will result in the motor clutch assembly being damaged.

Make sure that the contact pad and plunger in the door jamb are clean. You can clean it with a non metallic scotch brite pad. You also may need a door alignment as if the door is out of alignment it will be hard to close.

Sounds more like a problem with the latch/switch assembly not seeing that the door is closed, and trying to run the motor more and that would also explain the warning light, the BCM doesnt think the door is shut because the latch isnt telling it so

There are probably two sensors for th edoor, one for the motor and one for the BCM. Same software shops use, printable and more helpful than a book

First, reset the cable tension for the power door actuator. Also, check the center roller assembly on the door to make sure it's not bent. If it's slightly bent, replace it.
