⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before unplugging door wiring.
• ⚠️ Support the glass before removing regulator bolts. Unsupported glass can drop and break.
• ⚠️ Wear safety glasses and gloves when working inside the door. Door metal edges can be sharp.
• ⚠️ Do not turn the ignition ON with door connectors unplugged unless instructed. This may set warning codes.
• ⚠️ Keep fingers clear of the regulator tracks during testing.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect the battery

• Open the hood and locate the 12-volt battery.
• Use a 10mm socket and 3/8-inch drive ratchet to loosen the negative battery terminal.
• Move the cable away from the battery post so it cannot touch accidentally.
• Battery off protects electronics.

Step 2: Remove the front door screw covers

• Use a plastic pry tool set to gently open the small cover behind the inside door handle.
• Use the plastic pry tool set to lift the screw cover in the door pull pocket.
• A plastic pry tool is a soft tool that helps prevent scratches on trim.

Step 3: Remove the front door panel screws

• Use a Phillips #2 screwdriver to remove the screw behind the inside door handle.
• Use a Phillips #2 screwdriver to remove the screw in the door pull pocket.
• Place the screws in a magnetic parts tray.

Step 4: Release the door panel clips

• Start at the lower rear corner of the front door panel.
• Use a trim clip removal tool to pry outward near the first clip.
• Work along the bottom and sides with the trim clip removal tool until the clips release.
• A trim clip removal tool is a fork-shaped tool that pops clips loose without tearing the panel.
• Pull near each clip.

Step 5: Lift off the front door panel

• Use both hands to lift the panel straight upward off the window ledge.
• Hold the panel close to the door because wiring and cables are still attached.
• Unplug the power window switch connector by hand.
• Use a pick tool 90-degree gently if a connector lock tab is hard to release.

Step 6: Disconnect the inside handle cable

• Look behind the inside handle area for the cable attached to the handle.
• Use needle-nose pliers 6-inch to rotate the cable end out of the handle lever.
• Release the cable housing from its plastic bracket by hand.
• The cable housing is the outer sleeve that holds the moving cable in place.

Step 7: Peel back the vapor barrier

• Use your fingers and a plastic pry tool set to carefully peel the plastic vapor barrier away from the door.
• Peel it back far enough to access the regulator bolts, glass bolts, and motor connector.
• Do not tear it. This plastic keeps rainwater from entering the cabin.
• Butyl sealant is the sticky black rubber that seals the plastic to the door.

Step 8: Secure the window glass

• Place a glass suction cup handle 4-inch on the glass to help hold and control it.
• Use painter’s tape 1-inch to tape the glass to the upper door frame from both sides of the glass.
• Use several long strips of tape over the top of the door frame.
• Put a shop towel pack between tape and painted areas if you are worried about finish marks.
• Use more tape than less.

Step 9: Remove the glass mounting bolts

• Locate the two glass clamp bolts through the door access openings.
• Use a 10mm socket, 3/8-inch drive extension 6-inch, and 3/8-inch drive ratchet to loosen and remove the two glass bolts.
• Keep one hand on the glass suction cup handle 4-inch while removing the final bolt.
• Carefully slide the glass fully upward by hand if needed, then re-secure it with painter’s tape 1-inch.

Step 10: Disconnect the window motor connector

• Locate the electrical connector at the front window motor.
• Press the connector tab by hand and pull the connector straight off.
• Use a pick tool 90-degree gently if the lock tab is stuck.

Step 11: Remove the regulator and motor bolts

• Use a 10mm socket, 3/8-inch drive extension 6-inch, and 3/8-inch drive ratchet to remove the regulator mounting bolts.
• Use the same 10mm socket to remove the window motor mounting bolts if they are separate from the regulator bolts.
• Support the regulator with one hand as the last bolt comes out.
• Place all bolts in a magnetic parts tray.

Step 12: Remove the old regulator assembly

• Fold or angle the regulator slightly inside the door opening.
• Guide the regulator and motor assembly out through the large access opening.
• Do not force it against the glass, wiring, or sharp door edges.
• Slow movements prevent damage.

Step 13: Compare the new regulator

• Place the old and new regulators side by side.
• Confirm the mounting holes, motor connector, cable routing, and glass clamp positions match.
• If the new regulator did not include a motor, transfer the motor using a Phillips #2 screwdriver or 10mm socket as equipped.

Step 14: Install the new regulator assembly

• Guide the new regulator and motor into the door through the access opening.
• Start all regulator and motor bolts by hand first.
• Use a 10mm socket and torque wrench 5-60 Nm to tighten the regulator and motor mounting bolts.
• Torque to 9 Nm (80 in-lbs).

Step 15: Reconnect the motor and attach the glass

• Plug the motor connector in by hand until it clicks.
• Carefully lower the taped glass by hand into the regulator clamps.
• Use the glass suction cup handle 4-inch to control the glass while aligning the holes.
• Install the two glass mounting bolts by hand.
• Use a 10mm socket and torque wrench 5-60 Nm to tighten the glass mounting bolts.
• Torque to 8 Nm (71 in-lbs).

Step 16: Test the regulator before closing the door

• Reconnect the negative battery cable temporarily using a 10mm socket.
• Reconnect the power window switch connector by hand.
• Turn ignition ON.
• Run the window down and up in short movements.
• Watch that the glass moves smoothly in the front and rear channels.
• If the glass tilts or binds, turn ignition OFF and loosen the glass bolts with a 10mm socket, realign the glass, then retighten to 8 Nm (71 in-lbs).

Step 17: Reset the front auto-up window function

• With ignition ON, use the window switch to lower the window fully.
• Hold the switch DOWN for about 2 seconds after the glass reaches the bottom.
• Raise the window fully.
• Hold the switch UP for about 2 seconds after the glass reaches the top.
• Test auto-up and auto-down operation.

Step 18: Disconnect battery again for reassembly

• Turn ignition OFF.
• Use a 10mm socket to disconnect the negative battery cable again before handling wiring.

Step 19: Reseal the vapor barrier

• Press the vapor barrier back into the butyl sealant by hand.
• Use vapor barrier butyl sealant anywhere the original sealant no longer sticks.
• Make sure the bottom of the vapor barrier is sealed well.
• This prevents water from reaching the carpet and door panel.

Step 20: Reconnect the handle cable and wiring

• Clip the inside handle cable housing into the bracket by hand.
• Use needle-nose pliers 6-inch to guide the cable end into the handle lever.
• Reconnect the power window switch connector by hand.
• Make sure each connector clicks into place.

Step 21: Reinstall the front door panel

• Hang the top of the panel on the window ledge.
• Align the door panel clips with their holes.
• Press around the panel edges with your palm until the clips snap in.
• Replace broken clips with front door panel trim clips.

Step 22: Reinstall screws and covers

• Use a Phillips #2 screwdriver to reinstall the screw behind the inside handle.
• Use a Phillips #2 screwdriver to reinstall the screw in the door pull pocket.
• Snap both screw covers back into place by hand.

Step 23: Reconnect the battery

• Install the negative battery cable onto the battery post.
• Use a 10mm socket and torque wrench 5-60 Nm to tighten the terminal nut.
• Torque to 5 Nm (44 in-lbs).

✅ After Repair

• Test the front window from the driver master switch.
• Test the affected door’s own window switch.

• Check that the door locks, mirror switch, and speaker work if their connectors were disturbed.
• Spray a light amount of water on the outside glass area and check inside the door panel area for leaks.
• Listen for rattles while closing the door. A rattle usually means a loose clip, bolt, or cable.
