🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear door trim panel

• Use a 7mm socket and Phillips screwdriver to remove the visible panel screws.
• Use a trim clip tool to release the panel clips around the edge.
• Lift the panel upward to unhook it from the window ledge.
• Disconnect the electrical connector for the window switch.

Step 2: Remove the vapor barrier

• Peel back the vapor barrier carefully.
• Use a panel removal tool to separate the adhesive without tearing the barrier.
• Set it aside clean so it can be reused.

Step 3: Secure the glass

• Use painter's tape to hold the window glass fully up against the door frame.
• If the glass is already down, raise it by hand before disconnecting the regulator.
• Do not skip this step.

Step 4: Disconnect the glass from the regulator

• Remove the access cover or inner fasteners as needed with a Torx T20 screwdriver or Torx T25 screwdriver.
• Use a 10mm socket to loosen the glass-to-regulator clamp bolts, if equipped.
• Slide the glass fully up and tape it securely to the door frame.

Step 5: Remove the regulator assembly

• Unplug the window motor electrical connector.
• Use a 10mm socket and ratchet with extension bar to remove the regulator mounting bolts.
• Carefully guide the regulator out through the door access opening.
• Torque on reassembly: Tighten regulator mounting bolts to 8-10 Nm (71-89 in-lbs).

Step 6: Install the new regulator

• Feed the new regulator assembly into the door opening.
• Align the mounting holes and start all bolts by hand.
• Reconnect the electrical connector to the motor.
• Use a 10mm socket to tighten the mounting bolts.
• Torque regulator mounting bolts to 8-10 Nm (71-89 in-lbs).

Step 7: Reconnect the glass

• Lower the tape-supported glass carefully onto the regulator clamps.
• Install the glass clamp fasteners using a 10mm socket.
• Make sure the glass sits straight in the track before final tightening.
• Torque glass clamp bolts to 6-8 Nm (53-71 in-lbs).

Step 8: Test the window before reassembly

• Reconnect the battery negative cable using a 10mm socket.
• Cycle the window up and down with the switch.
• Check for smooth movement, noise, and correct alignment.
• If the glass binds, loosen the clamps and realign the glass.

Step 9: Reassemble the door

• Reinstall the vapor barrier with the original adhesive or new vapor barrier adhesive tape.
• Reconnect the door panel electrical connector.
• Hang the panel on the upper ledge and press the clips into place.
• Reinstall the screws with a 7mm socket and Phillips screwdriver.
• Torque panel screws snugly only; do not overtighten.
