🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear door trim panel

• Use a plastic pry tool set to pop off the trim cover at the inner door handle/armrest area.
• Remove visible screws using a Phillips #2 screwdriver and/or Torx T20 screwdriver (screw types vary by trim location).
• Use a trim clip removal tool to pop the perimeter clips free, working around the panel.
• Lift the panel upward to unhook it from the window ledge, then unplug connectors (window switch/courtesy light) by hand.
• Tip: Pull near each clip, not the middle.

Step 2: Remove the vapor barrier (water shield)

• Carefully peel the plastic vapor barrier back using a plastic pry tool set.
• Preserve the sticky butyl; if it’s messy or torn, plan to reseal with butyl tape.

Step 3: Secure the glass so it cannot fall

• Apply multiple strips of painters tape (2") from the outside of the glass over the door frame to hold the glass up.
• If the glass is loose, support it by hand while you add tape.

Step 4: Disconnect the window motor connector

• Unplug the window motor electrical connector by hand; use needle-nose pliers only if needed for the lock tab (don’t crush it).

Step 5: Separate the glass from the regulator

• Through the access openings, loosen (do not fully remove) the glass clamp fasteners using a 10mm socket (1/4" drive).
• With the clamps loosened, lift the glass fully up by hand and add more painters tape (2") to keep it parked.

Step 6: Remove the regulator/motor assembly

• If the regulator is bolted in: remove fasteners using a 10mm socket (1/4" drive) and 1/4" drive ratchet.
• If the regulator is riveted in: drill rivet heads using a drill with 1/4" drill bit, then push rivet bodies through with a trim clip removal tool or needle-nose pliers.
• Support the assembly with one hand and maneuver it out through the large access opening.

Step 7: Install the new regulator/motor

• Position the new assembly in the door and align mounting holes.
• If bolted: install bolts finger-tight, then Torque to 9 Nm (80 in-lbs) using a torque wrench (inch-pound).
• If riveted: install new rivets using a pop rivet gun (specialty), ensuring the regulator is tight and flush.

Step 8: Reattach the glass to the regulator

• Lower the glass carefully into the clamps (remove tape as needed) and ensure the glass sits evenly in both clamps.
• Tighten the clamp fasteners using a 10mm socket (1/4" drive).
• Torque to 9 Nm (80 in-lbs) using a torque wrench (inch-pound).

Step 9: Reconnect power and function-test before reassembly

• Reconnect the window motor connector by hand.
• Reconnect the battery negative terminal using a 10mm wrench.
• Turn ignition ON and test window up/down while watching for smooth travel and no cable grinding.
• Turn ignition OFF and disconnect the battery negative terminal again using a 10mm wrench before reinstalling trim.

Step 10: Reinstall the vapor barrier and door panel

• Reseat the vapor barrier; add butyl tape where needed (press firmly by hand).
• Reconnect door panel electrical connectors by hand.
• Hang the panel on the top lip first, then press clips in around the edges.
• Reinstall screws using a Phillips #2 screwdriver and/or Torx T25 screwdriver.
