🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the door trim panel

• Use a trim panel removal tool to pop off the trim pieces around the door handle and armrest.
• Use a Torx T20 screwdriver to remove the screws hidden behind the trim covers.
• Use the trim panel removal tool to release the door panel clips around the perimeter.
• Lift the panel upward to unhook it from the top edge of the door.
• Disconnect any electrical connectors carefully.

Step 2: Remove the moisture barrier

• Use a flat blade screwdriver and pick tool to carefully peel back the moisture barrier without tearing it.
• Keep the adhesive clean so the barrier can be resealed later.

Step 3: Secure the window glass

• Raise or position the glass so the mounting holes line up with the regulator access openings.
• Use masking tape across the top of the door frame to hold the glass in place.
• Two layers of tape helps prevent slipping.

Step 4: Disconnect the glass from the regulator

• Use a 10mm socket with a 1/4-inch ratchet and extension to remove the glass clamp bolts.
• Carefully slide the glass upward and secure it with more tape.

Step 5: Remove the old regulator

• Use a Torx T25 screwdriver or 10mm socket to remove the regulator mounting fasteners.
• Disconnect the window motor electrical connector if it is attached to the regulator assembly.
• Angle the regulator out through the large service opening in the door.

Step 6: Install the new regulator

• Feed the new regulator into the door opening and position it on the mounting points.
• Start all fasteners by hand before tightening.
• Torque to 8 Nm (71 ft-lbs) for the regulator mounting bolts unless your replacement kit specifies otherwise.
• Reconnect the motor connector.

Step 7: Reattach the glass

• Lower the taped glass carefully into the regulator clamps.
• Use a 10mm socket to tighten the glass clamp bolts.
• Torque to 8 Nm (71 ft-lbs) for the glass clamp bolts.
• Remove the masking tape only after the glass is fully secured.

Step 8: Test the window and reinstall the door panel

• Reconnect the battery negative cable.
• Use the window switch to test full up and full down travel.
• Reinstall the moisture barrier and press it firmly into the original adhesive.
• Reconnect all electrical connectors and hang the door panel on the upper door lip.
• Use the trim panel removal tool to snap the clips back in place.
• Reinstall all Torx T20 screws and trim covers.

✅ After Repair

• Listen for unusual cable noise or clicking during operation.
