Installation recommendations

Generally/typically for this type of part, the exact procedure for replacing the door lock may vary depending on the specific car design and equipment. Below is a practical general procedure for replacing an electric door lock.

1) Before assembly

• Check that it matches product number 913786 and that the part is as intended for the left rear door.
• Compare the connector, the shape of the lock, the attachment and the guide of the rods with the old part.
• Inspect the used part for cracks, damaged connector, bent parts or signs of excessive wear.
• Disconnect the battery before starting work, especially if you will be disconnecting the electrical connectors in the doors.

2) Necessary tools and materials

• Set of common hand tools
• Screwdrivers and bits for removing upholstery and fasteners
• Plastic levers for panel removal
• Clean rag
• Preparation for cleaning contacts or dirt as needed

3) Step-by-step assembly procedure

1. Open the door and prepare your work area so as not to damage the upholstery or paintwork.
2. Remove the interior lining of the rear door in the usual way for the given version of the car.
3. Carefully release the cover layers or access parts that prevent access to the lock.
4. Disconnect the electrical connector from the original lock.
5. Disconnect the tie rods or mechanical linkages of the handle and locking mechanism if they are part of the assembly.
6. Unscrew the fasteners of the old lock and remove the lock.
7. Compare the old and new part side by side, especially the position of the connector, mount and moving parts.
8. Insert the replacement lock into place and seat it into the correct position without force.
9. Install the fasteners and connect the tie rods or control mechanisms in the same configuration as the original part.
10. Connect the electrical connector and check that it is firmly seated.
11. Before fully assembling the door, check the basic locking and unlocking function.

• 4) Post-assembly checks and test drive/function verification
  • Try repeatedly locking and unlocking via central locking.
  • Verify the correct operation of the door handle and latch.
  • Check that the door closes securely and that the lock works smoothly without stuttering.
  • After folding the door, check that there is no creaking, looseness or pinched wiring.

  5) The most common assembly mistakes + how to avoid them

  • Swapping door side – always check it is the left rear door before fitting.
  • Incorrect connection of tie rods – note or document their position before disassembly.
  • Upholstery damage – use plastic levers and proceed with caution.
  • Insufficiently seated connector – after connecting, lightly check its fixation.
  • Premature folding of the door without a test – always check the function of the lock first, only then complete the installation.

  Reasons why the part is damaged

  • normal wear and tear on the mechanical and electrical parts of the lock
  • frequent use of central locking and repeated lock/unlock cycles
  • moisture entering the door and subsequent corrosion or deterioration of the mechanism
  • pollution of the internal mechanism with dust and dirt
  • damage to the connector, wiring or moving parts during previous repair
  • excessive force when opening or closing the door with an already partially damaged lock
