2004 Mazda: it starts to engage in the closing process it

This answer was rated:

I have a 2004 Mazda MPV. The power slide door will go to close, seems to get hung up, then re-opens. If it is helped along once it starts to engage in the closing process it will fully close and lock. Is there an adjustment that can be made?

Hello and welcome to Just, Super mechanic here. About your vehicle.

There has been a service bulletin for that type of concern. Here is what it states.

Body - Power Sliding Door Re-Opens After Closing

TSB: 09-026/05


^ 2002 - 2006 MPV vehicles equipped with Power Sliding Door (PSD)


After pressing any Power Sliding Door (PSD) switch, or manually pulling a rear door to close, the door may re-open fully after trying to close and latch.

Customers having this concern should have their vehicle repaired using the following repair procedure.


Rear door rubber wedges may be out of alignment causing the PSD control module to detect a load and re-open the door. To prevent this concern, perform inspection below.

A. Rear Door Rubber Wedge Inspection/Adjustment
1. Open affected Power Sliding Door (PSD).
2. Turn PSD main switch on dash to "OFF" position.
3. Inspect upper and lower rubber wedges on rear door.

^ If upper or lower rubber wedges are torn, severely worn, or damaged, replace wedges following Steps 5-9.
^ If upper or lower rubber wedges are not torn, severely worn, or damaged, use Steps 4 - 9 to realign existing wedges.
4. Remove affected wedge from door.
5. Peel off adhesive from back side of wedge.
6. Install wedge and tighten the two (2) mounting bolts just enough to allow wedge to align itself when door is pulled closed manually.
7. Pull door closed manually.
8. Open door and tighten wedge bolts without changing wedge position.
9. Apply a small amount of Krytox grease to female wedge on B-Pillar side. Proceed to "B. B-Pillar Electrical Contacts Inspection".
B. B-Pillar Electrical Contacts Inspection NOTE: The PSD electrical contacts must be clean for proper operation of the PSD system.
1. Duplicate the concern.
^ If the concern can be duplicated, and the vehicle was built BEFORE April 21, 2004, proceed to "B-Pillar - Rear Sliding Door Contacts Replacement".
^ If the concern can be duplicated, and the vehicle was built AFTER April 21, 2004, lightly polish the B-pillar contacts and rear door contacts with crocus cloth and spray contacts with electrical contact cleaner (Deoxit # XXXXX or equivalent). Do not replace any parts, repair is complete.

2. Open one side rear sliding door.
