🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear door trim panel

• Use a trim removal tool to pry off the trim covers and access screws.
• Remove the visible fasteners with a Phillips screwdriver and 10mm socket.
• Carefully pop the panel clips loose around the edge of the door.
• Lift the door panel upward to unhook it from the top ledge.
• Work slowly to avoid breaking clips.

Step 2: Disconnect electrical connectors and remove the vapor barrier

• Unplug the window switch connector and any courtesy light connector.
• Peel back the vapor barrier carefully. Reuse it if it is still intact.
• Use a pick tool to release stubborn adhesive without tearing the barrier.

Step 3: Secure the glass

• Raise the glass fully if it still operates, then tape it to the door frame using painter’s tape.
• If the glass is already stuck or loose, support it by hand while the regulator is disconnected.
• Do not let the glass hang unsupported.

Step 4: Disconnect the glass from the regulator

• Remove the access hole covers inside the door.
• Use a 10mm socket to loosen the glass clamp fasteners.
• Slide the glass up slightly by hand if needed, then lift it out of the regulator clamps.

Step 5: Remove the old regulator

• Use a 10mm socket and 12mm socket to remove the regulator mounting bolts.
• Unplug the motor connector from the regulator assembly.
• Rotate and maneuver the regulator out through the largest service opening in the door.

• Tighten the regulator bolts with a torque wrench to 7.5 Nm (66 in-lbs).

Step 7: Reattach the glass

• Lower the taped glass carefully into the regulator clamps.
• Align the glass with the clamp openings and tighten the glass fasteners with a 10mm socket.
• Torque the glass clamp bolts to 7.5 Nm (66 in-lbs).
• Remove the painter’s tape after the glass is fully secured.

Step 8: Test the window before reassembly

• Reconnect the battery temporarily and cycle the window switch.
• Check that the glass moves smoothly and stays aligned in the tracks.
• If the window binds, stop and realign the glass before reinstalling the panel.
• Disconnect the battery again before finishing the door assembly.

Step 9: Reinstall the vapor barrier and door panel

• Press the vapor barrier back into place with firm even pressure.
• Reconnect all electrical connectors.
• Hang the door panel on the top edge first, then press the clips into place.
