🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear door trim panel

• Use a trim removal tool to pop off the trim covers and pry the door panel loose.
• Use a Phillips screwdriver and 10mm socket to remove the visible screws and bolts.
• Disconnect any electrical connectors for the switch panel and set the panel aside.

Step 2: Remove the vapor barrier

• Use your hands to slowly peel back the plastic vapor barrier.
• Keep the adhesive clean so you can reinstall it later.
• Do not tear the barrier if you can avoid it.

Step 3: Secure the window glass

• Use painter’s tape to hold the glass in the fully raised position from the outside of the door.
• If the glass is stuck lower, lift it by hand carefully before taping it in place.

Step 4: Disconnect the glass from the regulator

• Use a 10mm socket to remove the bolts or fasteners holding the glass to the regulator clamps.
• Support the glass with one hand while removing the last fastener.
• Lift the glass out of the channel area if needed and store it safely.

Step 5: Remove the regulator assembly

• Use a 10mm socket and short extension to remove the regulator mounting bolts.
• Use a 12mm socket if any track or motor bolts are larger on your door.
• Unplug the window motor connector.
• Work the regulator assembly out through the large access opening in the door.

Step 6: Install the new regulator

• Feed the new regulator into the door through the access opening.
• Align the mounting holes and start all bolts by hand.
• Reconnect the motor electrical connector.
• Torque to 7-9 Nm (62-80 in-lbs) for regulator mounting bolts unless the fastener head or service data on the part calls for a different spec.

Step 7: Reconnect and secure the window glass

• Lower or raise the regulator until the glass clamp openings line up.
• Set the glass back into the clamps.
• Use a 10mm socket to tighten the glass-to-regulator fasteners.
• Torque to 7-9 Nm (62-80 in-lbs) for the glass clamp bolts.

Step 8: Test the window before reassembly

• Reconnect the battery negative cable.
• Turn the ignition on and use the window switch to run the glass up and down.
• Make sure the glass moves evenly and does not bind or click.
• Disconnect the battery again before finishing the panel install if needed.

Step 9: Reinstall the door panel

• Press the vapor barrier back into place using the original adhesive or butyl sealant.
• Reconnect all electrical connectors.
• Hang the door panel on the top edge first, then press in the clips.
• Reinstall all screws, bolts, and trim covers with the Phillips screwdriver and 10mm socket.
