Power Window Motor - Front

This procedure covers the removal and replacement of the front power window motor on a 2017 Maserati Levante, including door panel removal, window regulator access, and electrical disconnection.

Warnings

Tools required

Parts

• Front power window motor × 1 — Use OEM specification
• Door panel retaining clips × 5 — Have spares available
• Vapor barrier adhesive × 1 — If vapor barrier is damaged

Preparation

1. Park vehicle on level surface and engage parking brake
2. Roll the affected window to the mid-point position before starting work to provide access to regulator bolts
3. Disconnect negative battery terminal and wait 2 minutes for airbag system capacitors to discharge
4. Ensure you have replacement door panel clips available as original clips often break during removal
5. Photograph door panel and switch locations before disassembly for reference

Procedure

1. 1

   Disconnect battery and remove door trim components
   Disconnect the negative battery cable. Remove the door handle trim bezel by carefully prying with a panel tool. Remove the door pull handle cover by releasing clips. Remove any speaker grilles or small trim pieces from the door panel.

   Battery Terminal Bolts6 Nm (4 lb-ft)
2. 2

   Remove window switch assembly
   Carefully pry up the window switch control panel from the armrest using a panel tool. Disconnect the electrical connectors by pressing the release tabs. Set the switch assembly aside in a safe location.
3. 3

   Remove door panel fasteners
   Remove all Torx screws securing the door panel (typically located in the pull handle recess, lower door edge, and behind trim pieces). Remove the single bolt behind the door handle bezel opening. Check carefully for any hidden fasteners.
   Torque spec

   Cover Screws11 Nm (8 lb-ft)
4. 4

   Detach and remove door panel
   Starting at the bottom rear corner, use panel removal tools to release the retaining clips around the perimeter of the door panel. Lift the panel upward to disengage it from the window sill, then pull away from the door. Disconnect any remaining electrical connectors for ambient lighting or other accessories. Set the door panel on a padded surface to avoid scratches.
   ⚠Apply steady, even pressure when releasing clips — forcing the panel can crack mounting points
5. 5

   Access motor through vapor barrier
   Carefully peel back the plastic vapor barrier just enough to access the window motor and regulator assembly. If necessary, cut a new access hole using a sharp blade, but preserve as much of the barrier as possible. Secure the peeled section with masking tape to keep it out of the way.
6. 6

   Secure window glass
   Use masking tape to secure the window glass in the UP position to prevent it from dropping when the regulator is disconnected. Tape the glass to the door frame from the outside of the vehicle using several strips of strong tape.
   ⚠Failure to secure the glass can result in it falling and shattering
7. 7

   Disconnect window motor electrical connector
   Locate the power window motor electrical connector. Press the locking tab and disconnect the connector from the motor. Inspect the connector terminals for corrosion or damage. Note the connector orientation for reinstallation.
8. 8

   Remove motor mounting bolts
   Locate the three mounting bolts securing the window motor to the regulator assembly. Using a 10mm socket with extension, remove all motor mounting bolts. Support the motor while removing the final bolt to prevent it from falling.
   ℹ️The motor is connected to the regulator mechanism and may be under slight tension

   Module Mounting Bolts8 Nm (6 lb-ft)
9. 9

   Separate motor from regulator
   Carefully disengage the motor gear from the regulator mechanism. The motor may need to be rotated slightly to align the gear for removal. Extract the motor through the door access opening. Inspect the regulator gear teeth for damage or wear.
10. 10

    Install new window motor
    Position the new motor at the access opening and align the motor gear with the regulator mechanism. Ensure proper gear engagement before proceeding. Position the motor against the mounting surface and thread in all three mounting bolts hand-tight. Torque the mounting bolts to specification in a star pattern to ensure even pressure.

11. 11

    Reconnect electrical and test operation
    Connect the electrical connector to the new motor, ensuring it clicks into place. Reconnect the battery negative terminal. Before reinstalling the door panel, test window operation through several complete cycles. Verify smooth operation with no binding or unusual noises. If window operates correctly, disconnect the battery again for door panel reinstallation.
    ⚠Keep hands clear of window and regulator mechanism during testing

12. 12

    Reseal vapor barrier and reinstall door panel
    Reattach the vapor barrier using the original adhesive or new vapor barrier adhesive if needed. Ensure a complete seal to prevent water intrusion and wind noise. Reconnect all electrical connectors to the door panel. Position the door panel, engaging the upper edge onto the window sill first, then pressing firmly around the perimeter to seat all clips. Reinstall all fasteners and trim pieces in reverse order of removal.

Reassembly

1. Install door panel components in reverse order of removal, ensuring all clips are properly seated
2. Torque all fasteners to specification — do not overtighten trim screws as this can crack plastic
3. Reconnect battery and perform window initialization procedure if required by the vehicle
4. Test all door functions including locks, switches, and window operation before completing the job

Verification

• Operate the window through several complete up and down cycles to verify smooth operation
• Check for any binding, unusual noises, or slow operation that might indicate improper installation
• Verify the window seats properly at the full-up position and the weather seals make contact
• Test the one-touch auto up/down function (if equipped) operates correctly
• Perform window auto-initialization if required: With ignition on, hold window switch down until fully open, continue holding for 2 seconds, then hold switch up until fully closed and continue holding for 2 seconds
• Check all door panel trim pieces are secure with no rattles or loose components
• Verify all door panel switches and accessories function properly
• Inspect for any gaps between door panel and door frame
