⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before starting. The front doors have side airbags and power wiring inside.
• ⚠️ Support the glass securely with tape before loosening it from the regulator so it doesn’t fall and crack.
• ⚠️ Use jack stands or wheel chocks if you park on an incline so the vehicle cannot roll.
• ⚠️ Wear safety glasses when drilling rivets and working inside the door to protect your eyes from metal shavings.
• ⚠️ Work gently around the door wiring harness and airbag wiring. Do not pull on yellow airbag connectors.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove trim covers and door panel screws

• Use a small flathead screwdriver to gently pry out the small plastic cover behind the inside door handle; this reveals a screw. Twist, don’t stab, to avoid marks.
• Use the trim removal tool to pop up the small trim cap in the pull handle pocket (where you pull the door closed); this also hides a screw.
• Remove the exposed screws with a 7mm socket and ratchet. Keep them labeled so you know where they go.
• If there is a Torx screw at the bottom edge of the panel, remove it with a Torx T20 screwdriver.

Step 2: Remove the window switch and disconnect wiring

• Use a trim removal tool to gently pry up the window switch panel from the armrest, starting at the rear edge.
• Lift the switch panel and disconnect the electrical connectors by pressing the locking tabs with your finger or a small flathead screwdriver.
• Set the switch panel aside somewhere safe.

Step 3: Remove the door trim panel

• Starting at the bottom corner of the door, slide a trim removal tool between the panel and the metal door frame and gently pry to release the first clip.
• Work your way around the sides and bottom of the panel, popping out the plastic clips. Use your hands to pull once clips start.
• Once all clips are loose, lift the door panel straight up to unhook it from the window ledge.
• Reach behind the panel and disconnect any remaining connectors (courtesy light, etc.) by hand or with needle-nose pliers on the tab if needed.
• Unclip the interior door handle cable from the handle assembly by prying the plastic retainer open with a small flathead screwdriver and lifting the cable end out.
• Set the door panel aside on a blanket to avoid damage.

Step 4: Remove the moisture barrier (vapor barrier)

• The thin plastic sheet stuck to the door is the vapor barrier; it keeps moisture away from the interior.
• Use a utility knife to gently cut through heavy butyl glue if needed and peel the barrier back slowly from the top and sides.
• Try not to tear it; let it hang or tape it up out of the way with masking tape.

Step 5: Secure the window glass

• If the glass is up: run two or three strips of masking tape from the outside of the glass, over the top of the door frame, and down the inside to hold it in place.
• If the window is stuck down but still attached, you may need to temporarily reconnect the switch and battery, move the glass to where mounting bolts are visible through the access holes, then disconnect battery again. Only power up long enough to move glass.

Step 6: Detach the glass from the regulator

• Look through the large opening in the inner door skin to find the two glass clamp bolts (near the bottom of the glass).
• Use a 10mm socket and ratchet to loosen (do not remove) these clamp bolts until the glass can slide up out of the regulator jaws.
• Carefully slide the glass fully up into the door frame by hand and add more masking tape over the top of the door to secure it.

Step 7: Disconnect the regulator motor wiring

• Locate the window motor on the regulator assembly (near the middle/front of the door).
• Press the lock tab and unplug the motor connector by hand or using a small flathead screwdriver to help release the tab.
• If the connector is dirty, spray lightly with electrical contact cleaner and let it dry.

Step 8: Drill out factory rivets (if equipped)

• GM often uses rivets to mount the regulator. Look for round-headed rivets around the regulator tracks.
• Put on your safety glasses.
• Use an electric drill with a 5mm drill bit and drill out the center of each rivet head. Go slowly until the head pops off.
• Push the remaining rivet bodies through into the door cavity; they will fall inside but won’t cause problems.

Step 9: Remove bolts and lift out the old regulator

• Any regulator mounting bolts that are not rivets should be removed with a 10mm socket and ratchet.
• If the motor is separately bolted to the door, remove the three motor screws using a Torx T30 screwdriver. Torque for reassembly: 8 N·m (71 in-lbs).
• Collapse the regulator slightly inside the door and carefully maneuver it out through the largest opening in the inner door skin. Rotate as needed; move slowly.

Step 10: Prepare the new regulator and motor

• If your new part includes the motor already installed, you can skip motor transfer.
• If you need to transfer the motor, align the old motor on the new regulator and install with the existing screws using a Torx T30 screwdriver. Torque to 8 N·m (71 in-lbs).
• Make sure the cables are routed smoothly and not twisted.

Step 11: Install the new regulator assembly

• Feed the new regulator into the door through the large access opening, just like you removed the old one.
• Align the mounting holes of the regulator with the holes in the door.
• If you’re using rivets (factory method):
• Load a 5mm rivet into the rivet gun, insert the rivet through the aligned holes, and pull the rivet until it snaps.
• Repeat for all mounting points.
• If you’re using bolts and nuts (DIY alternative):
• Insert an M6x1.0 flange bolt from the inside through the regulator and door holes.
• Install an M6 lock nut on the back using a metric combination wrench to hold the nut and a 10mm socket to tighten the bolt.
• Apply a drop of medium strength threadlocker to each bolt before tightening.
• Tighten to about 10 N·m (89 in-lbs).
• Do not fully torque until all fasteners are started, then tighten evenly.

Step 12: Reconnect the motor wiring and attach the glass

• Plug the motor connector back in by hand until it clicks.
• Carefully remove the masking tape holding the glass while guiding the glass down into the new regulator clamps.
• Once the glass is seated in the clamps, snug the clamp bolts with a 10mm socket. Torque to 10 N·m (89 in-lbs).

Step 13: Test window operation (before closing door up)

• Temporarily reconnect the window switch connector and the negative battery cable using a 10mm socket.
• Turn the ignition to ON (engine off) and test the window up and down several times.
• Listen for smooth, quiet movement. The glass should move straight without tilting or binding.
• If it binds, loosen the regulator mounting bolts slightly with a 10mm socket, move the assembly a bit, retighten, and test again.
• Once satisfied, turn ignition off and disconnect the negative battery cable again before reassembling.

Step 14: Reinstall the vapor barrier

• Press the plastic vapor barrier back into place along the door edges.
• If the original butyl adhesive no longer sticks, apply fresh butyl sealant strip around the perimeter and press the plastic firmly into it.
• Make sure there are no large gaps; this keeps water off the inside of the door panel.

Step 15: Reinstall the door panel

• Reconnect any electrical connectors (courtesy light, etc.) by hand until they click.
• Reattach the interior handle cable: hook the cable end into the handle, then snap the plastic retainer back into place using your fingers or needle-nose pliers.
• Hang the top of the door panel on the window ledge by lining up the upper hooks and pushing down.
• Once the top is seated, line up the side and bottom clips with their holes and firmly tap around the edges with your palm to snap them in.
• Replace any broken clips with new ones by pushing them into the panel before mounting.

Step 16: Reinstall screws, switch panel, and trim caps

• Reinstall the screws in the pull handle and behind the interior handle using a 7mm socket and ratchet. Torque to about 2 N·m (18 in-lbs) (snug, not very tight).
• If you removed any Torx screws, reinstall them with a Torx T20 screwdriver to about the same snug tightness.
• Reconnect the window switch connectors and press the switch panel back into the armrest until it snaps in.
• Press the plastic trim caps back into place by hand.

Step 17: Final reconnect and calibration

• Reconnect the negative battery cable with a 10mm socket and tighten it securely. Torque to about 15 N·m (11 ft-lbs) (firm, not over-tight).
• Turn ignition to ON and test the front window again from both the local switch and the driver’s master switch.
• If auto-up/down does not work correctly: hold the switch to fully lower the window, keep holding for 2–3 seconds, then raise it fully and hold for another 2–3 seconds. This can relearn the end positions.

✅ After Repair

• Test the window several times for smooth movement and proper sealing at the top when closed.
• Check that the door locks, interior handle, and mirror switch (if on that panel) all work correctly.
• Drive slowly on a rough road and listen for rattles from the door; if you hear anything, a clip or screw may not be fully seated.
• Verify that no warning lights (especially airbag) appear on the dash after reconnecting the battery.
