⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before working; the rear door has a side airbag, and you’ll unplug electrical connectors.
• ⚠️ Support the glass with tape or a helper when it’s unbolted so it doesn’t drop and shatter.
• ⚠️ Work with the ignition OFF whenever connectors are unplugged.
• ⚠️ Use proper jack stands if you ever raise the vehicle, but this repair can be done on the ground.
• ⚠️ Wear safety glasses and gloves to protect from sharp metal edges inside the door.

📋 Before You Begin

• Park your Camry on level ground, engage the parking brake, and make sure the ignition is OFF.
• Lower the rear window you’re working on to about halfway if it still moves; this can make glass access easier later. If it’s stuck, you can still proceed.
• Disconnect the negative battery terminal using a 10mm socket and move the cable aside so it cannot spring back.
• Open the rear door fully to give yourself space to work.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove rear door trim panel

• Use a flathead screwdriver wrapped in tape or a trim removal tool (plastic) to gently pry off the small trim cover behind the interior door handle. This exposes a screw.
• Use a Phillips #2 screwdriver to remove the screw behind the handle.
• Pry up the window switch panel from the armrest with the trim removal tool (plastic), starting at the rear edge. Lift it out carefully.
• Disconnect the window switch electrical connector by pressing the tab with your finger or needle-nose pliers and pulling straight out.
• Remove the screw in the armrest area (exposed under the switch panel) using a Phillips #2 screwdriver.
• At the bottom edge of the door panel, check for any visible screws and remove them with the Phillips #2 screwdriver if present.
• Use the panel clip removal tool or trim removal tool (plastic) to pop the plastic clips around the edge of the door panel. Start at the bottom corner and work your way around. Clips will pop loudly; that’s normal.
• Lift the door panel straight up and off the door. Unhook any cables for the interior door handle latch by rotating the plastic retainers and releasing the cable ends with your fingers.
• Set the door panel somewhere safe so you don’t damage the trim.

Step 2: Remove moisture barrier and expose regulator

• The moisture barrier is the plastic sheet stuck to the metal door with sticky butyl. Carefully peel it back with your hands starting at a corner. Use a trim removal tool (plastic) if needed.
• Try not to tear it, and keep the sticky side clean so you can reuse it.
• Peel it back enough to see the entire window regulator (metal rail and cables) and the motor assembly.

Step 3: Secure the glass

• If the glass is still attached to the regulator and can move, raise or lower it by hand (or reconnect the switch briefly with the battery reconnected if needed, then disconnect again) until you can see the glass mounting bolts through the access holes.
• Once the glass is in a workable position, use masking tape to tape the glass to the upper door frame from the outside. Run several strips from the outside of the glass over the top of the door frame and down the inside.
• Use at least 3–4 tape strips for safety.

Step 4: Detach glass from regulator

• Look through the access holes in the inner door panel to find the two bolts that clamp the glass to the regulator’s carrier.
• Use a 10mm socket with 1/4" drive ratchet to loosen and remove these two glass bolts.
• Torque when reinstalling glass bolts later: 13 Nm (115 in-lb).
• Once removed, gently push the glass up fully into the door frame by hand, keeping it aligned in the tracks.
• Add more masking tape at the top to hold the glass in the fully up position so it cannot slide down.

Step 5: Disconnect window motor and regulator fasteners

• Locate the electrical connector at the window motor. Press the tab and unplug it by hand or with needle-nose pliers.
• Find all the regulator mounting bolts (usually 3–4) and the motor mounting bolts (usually 3) on the inner door metal.
• Use a 10mm socket and 1/4" drive ratchet to remove all regulator and motor bolts.
• Torque for regulator and motor bolts during installation: 8 Nm (71 in-lb).
• Support the regulator with one hand as you remove the last bolts so it doesn’t fall inside the door.

Step 6: Remove the old regulator and motor assembly

• Carefully maneuver the regulator and motor assembly out through the largest opening in the door metal. You may need to rotate it slightly to clear the opening.
• Take a picture of its orientation before removal.
• If your new regulator does not include the motor, transfer the motor now: remove the three motor screws with a 10mm socket or Phillips #2 screwdriver (depending on design) and install it on the new regulator in the same orientation. Torque to 5–6 Nm (44–53 in-lb).

Step 7: Install the new regulator assembly

• Feed the new regulator (and motor) into the door through the same opening, matching the orientation you saw earlier.
• Align the mounting holes of the regulator and motor with the threaded holes in the door.
• Hand-start all regulator and motor bolts using a 10mm socket to avoid cross-threading.
• Once all bolts are started, tighten them evenly with the 10mm socket and 1/4" drive ratchet.
• Use a torque wrench with the 10mm socket to torque all regulator and motor bolts to 8 Nm (71 in-lb).
• Reconnect the motor electrical connector by pushing it in until it clicks.

Step 8: Reattach the glass to the regulator

• Carefully remove the upper masking tape from the glass, but keep a hand on the glass so it does not slide.
• Lower the glass slowly by hand into the door until the mounting points line up with the new regulator carrier clamps (visible through the access holes).
• Reinstall the two glass bolts using the 10mm socket and 1/4" drive ratchet.
• Torque the glass bolts with a torque wrench and 10mm socket to 13 Nm (115 in-lb).
• Remove any remaining tape from the glass and door frame.

Step 9: Test the window operation (before sealing door)

• Temporarily reconnect the rear window switch to its connector in the door.
• Reconnect the negative battery cable with a 10mm socket and snug it down. Torque: 5 Nm (44 in-lb) is sufficient; don’t overtighten.
• Turn the ignition to ON (engine not required).
• Use the rear window switch to run the window up and down several times. Watch for smooth, quiet movement with no binding or tilting.
• If it binds or tilts, stop, lower slightly, and recheck that the glass sits correctly in the tracks and is firmly bolted to the regulator.
• Once operation is confirmed, turn ignition OFF and disconnect the negative battery cable again with the 10mm socket before reassembling the door.

Step 10: Reinstall moisture barrier

• Press the plastic moisture barrier back into place along its original outline on the door metal.
• If the butyl seal is not sticky enough, apply fresh butyl tape/sealant by hand around the perimeter, then press the plastic into it.
• Make sure there are no large gaps so water cannot leak into the door panel.

Step 11: Reinstall door trim panel

• Reconnect any interior door handle cables: hook the cable ends into the handle lever, then clip the plastic retainers back into place by hand.
• Reconnect the window switch electrical connector and place the switch panel aside for now.
• Hang the top of the door panel on the top edge of the door by engaging the upper lip first.
• Once aligned, press around the edges of the door panel with your hands to snap all clips back into their holes. Work around the edge until all clips seat.
• Reinstall any screws at the bottom of the door panel using the Phillips #2 screwdriver.
• Reinstall the armrest screw with the Phillips #2 screwdriver and then snap the switch panel back into the armrest by hand.
• Reinstall the screw behind the interior door handle with the Phillips #2 screwdriver, then press the small trim cover back into place by hand.

Step 12: Final electrical reconnection and test

• Reconnect the negative battery cable one final time using the 10mm socket and torque wrench, tightening to about 5 Nm (44 in-lb).
• Turn the ignition to ON and test:
  • Rear window up/down from the rear door switch
  • Rear window up/down from the driver’s master switch
• Listen for abnormal noises and verify the glass seals properly at the top.

✅ After Repair

• Run the window through its full travel several times to confirm smooth operation and that it seats firmly when fully up.
• Check inside the car and under the door for any loose clips or screws you may have missed.
• Verify that the rear door locks, handle, and side airbag warning light all function normally.
• After the first drive in rain or a car wash, check the rear door area for any signs of water intrusion; if present, reseal the moisture barrier.
