⚠️ Safety & Precautions

• Disconnect the negative battery cable before starting. The door has side airbag wiring and power window circuits.
• Support the window glass with tape before removing the regulator so the glass does not drop.
• Be careful around the side curtain/door airbag area. Do not probe yellow connectors.
• The window motor and regulator can pinch fingers. Keep hands clear while moving the glass.
• If the door has a moisture barrier, do not tear it. Reinstall it fully to prevent water leaks.

Step 4: Secure the window glass

• If the glass is movable, raise it by hand and secure it to the door frame with painter's tape.
• Make sure the glass cannot fall when the regulator is removed.

Step 5: Disconnect the regulator from the glass

• Use a 10mm socket to remove the glass clamp fasteners through the access openings in the door.

• Leave the glass taped in place once free from the regulator.

Step 6: Remove the regulator and motor assembly

• Use a 10mm socket and ratchet with an extension bar to remove the regulator mounting bolts.
• Disconnect the window motor electrical connector.

• Torque to 8 Nm (71 in-lbs).

Step 9: Test window operation before reassembly

• Reconnect the battery temporarily and turn the key on.

Step 10: Reinstall the moisture barrier and door panel
