⚠️ Safety & Precautions

• Disconnect the 12V battery negative terminal before working inside the door. The hybrid system is not involved, but the power window circuit is.
• Support the glass with tape before removing the regulator so the window does not drop.
• Use care around the side airbag area in the door. Do not probe yellow connectors.
• Keep fingers clear of the window tracks and regulator arms. The mechanism can pinch hard.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear door trim panel

• Use a flat trim tool and trim panel clip tool to pop off the switch bezel and visible trim covers.
• Use a Phillips screwdriver and 10mm socket to remove the screws hiding behind the trim pieces and in the pull handle.
• Lift the door panel upward to release it from the door shell.
• Disconnect the window switch connector and any courtesy light connector.

Step 2: Remove the moisture barrier

• Peel back the inner vapor barrier carefully by hand.
• Use a trim tool if needed to avoid tearing the adhesive.
• Keep the barrier clean and sticky.

Step 3: Tape the glass in place

• Raise the window glass to the fully up position if possible.
• Use painter's tape across the top of the door frame and glass to hold it securely.
• If the glass is already down, guide it by hand into the up position before taping.

Step 4: Remove the regulator fasteners

• Use a 10mm socket, ratchet, and extension bar to remove the regulator bolts inside the door.
• Use a Torx T20 screwdriver if any regulator or motor screws are Torx style.
• Remove the fasteners holding the glass clamps and regulator track.
• Torque on installation: 7.5 Nm (66 in-lbs) for the regulator mounting bolts unless your replacement part specifies otherwise.

Step 5: Remove the old regulator assembly

• Lower or maneuver the assembly out through the largest access opening in the door shell.
• If the motor is attached to the regulator, remove the assembly as one unit.
• Watch the glass edges and door latch mechanism as you remove it.

Step 6: Install the new regulator

• Feed the new regulator into the door and line up the mounting points.
• Use the 10mm socket to install the mounting bolts finger-tight first.
• Attach the glass clamps to the window glass carefully.
• Torque to 7.5 Nm (66 in-lbs) for the regulator and glass clamp fasteners unless the part instructions say different.

Step 7: Test window movement before reassembly

• Reconnect the 12V battery negative terminal temporarily.
• Reconnect the window switch and cycle the window up and down.
• Make sure the glass moves straight and does not bind or tilt.
• Disconnect the battery again before final reassembly if you need to adjust the regulator.

Step 8: Reinstall the vapor barrier and door panel

• Press the vapor barrier back into place so water stays out of the door.
• Reconnect all electrical connectors.
• Hang the door panel on the upper lip first, then press the clips back in.
• Reinstall the screws using a Phillips screwdriver and 10mm socket.

✅ After Repair

• If auto-up/down does not work, perform window initialization using switch hold-up and hold-down relearn until the function returns.
• Check for wind noise and water leaks around the door panel.
