⚠️ Safety & Precautions

• ⚠️ Disconnect the battery negative terminal before working; the front doors contain side airbags and powered components.
• ⚠️ Wait at least 90 seconds after disconnecting the battery before unplugging any connectors near the side airbag.
• ⚠️ Support the door glass securely with tape to avoid it dropping and shattering.
• ⚠️ Work with the ignition OFF; never cycle the key while connectors are unplugged in the door.
• ⚠️ Keep screws and clips organized; lost or loose fasteners can cause rattles or poor window alignment.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Lower the affected window until it is about halfway down if it still moves; this makes access to the glass bolts easier.
• Turn ignition OFF and remove the key.
• Disconnect the battery negative (−) cable using a 10mm socket, then wait at least 90 seconds before working on the door.
• Open the door fully and ensure you have enough space to swing the door open and move around comfortably.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove door handle and switch trim covers

• Use a plastic trim removal tool to gently pry up the window switch panel at the front edge of the armrest.
• Lift the panel and unplug the switch connector by pressing the tab with a flat blade screwdriver if needed.
• Use the plastic trim removal tool to pop off the small trim cover behind the interior door handle to expose a screw.

Step 2: Remove door panel screws

• Use a Phillips #2 screwdriver to remove the screw behind the interior door handle.
• Use the Phillips #2 screwdriver to remove the screw inside the armrest pocket.
• Place screws in a small container so you do not lose them.

Step 3: Remove the door trim panel

• Insert a plastic trim removal tool between the bottom edge of the door panel and the metal door.
• Pry gently to release the first plastic clip, then move along the edge releasing all clips using the panel clip removal tool as needed.
• Once all clips are loose, lift the door panel straight up to unhook it from the window ledge.
• Support the panel and unplug all connectors using your flat blade screwdriver to release locking tabs if necessary.
• Disconnect the interior door handle cable by flipping the plastic retainer open and unhooking the cable end using needle-nose pliers if needed.

Step 4: Remove the moisture barrier

• Carefully peel back the plastic sheet (moisture barrier) starting at a corner, using your hands and a utility knife only to cut any added tape, not the plastic itself.
• Do not tear the plastic; let the sticky butyl sealant stay on it as much as possible.
• Peel it back enough to access the regulator, motor, and glass mounting points.

Step 5: Secure the glass

• If the window is not already halfway, temporarily plug in the window switch and reconnect the battery negative with a 10mm socket, move the glass, then disconnect battery again and unplug the switch.
• With the glass around halfway 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 the glass in place.
• Use wide tape for better grip

Step 6: Loosen glass-to-regulator bolts

• Look through the access holes in the inner door panel to locate the two glass mounting clamps.
• Use a 10mm socket and ratchet to loosen (do not fully remove) the two glass clamp bolts.
• Once loose, gently slide the glass fully up by hand and add more masking tape to secure it to the door frame.

Step 7: Remove the old regulator and motor

• Unplug the window motor electrical connector using a flat blade screwdriver to press the release tab if necessary.
• Use a 10mm socket and ratchet with 3" extension to remove all regulator mounting bolts (usually 4–6 bolts around the rail and motor).
• Support the regulator with one hand as you remove the last bolt to prevent it dropping inside the door.
• Rotate and maneuver the regulator and motor assembly out through the access opening.

Step 8: Transfer any needed parts to the new regulator

• Compare the old and new regulator assemblies side by side on a clean surface.
• If any brackets or plastic guides need transferring, move them over using a 10mm socket or Phillips #2 screwdriver as required.
• New assemblies usually arrive ready to install

Step 9: Install the new regulator and motor

• Feed the new regulator assembly into the door cavity, positioning it as the old one was.
• Align the regulator and motor mounting holes with the threaded holes in the door.
• Install all regulator and motor bolts finger-tight by hand first.
• Use a 10mm socket and ratchet to snug the bolts evenly.
• Use a torque wrench with 10mm socket to tighten regulator and motor bolts to 7 N·m (62 in‑lb).
• Reconnect the motor electrical connector; if dirty, spray lightly with electrical contact cleaner and let dry first.

Step 10: Attach the glass to the new regulator

• Carefully remove the top strips of masking tape and lower the glass by hand until the glass mounting areas align with the regulator clamps.
• Hold the glass gently in position while you snug the two clamp bolts with a 10mm socket and ratchet.
• Use a torque wrench with 10mm socket to tighten the glass clamp bolts to 9 N·m (80 in‑lb).
• Remove all remaining tape from the glass and door frame.

Step 11: Temporary power-up and window test (door still apart)

• Reconnect the window switch to the door harness.
• Reconnect the battery negative terminal with a 10mm socket.
• Turn ignition to ON (engine off) and run the window up and down several times to verify smooth movement and no binding.
• If movement is good, lower the window about 2–3 cm from fully closed, then turn ignition OFF and disconnect the battery negative again using the 10mm socket.
• Unplug the window switch so you can refit the door panel.

Step 12: Reinstall the moisture barrier

• Carefully press the plastic moisture barrier back into its original position, matching all holes and edges.
• If the butyl sealant no longer sticks well, apply fresh door moisture barrier butyl sealant tape along the edges by hand.
• Firmly press along the entire perimeter to avoid air and water leaks.

Step 13: Reinstall the door trim panel

• Reconnect all electrical connectors to the window switch, door lock switch, and any courtesy light by hand.
• Reconnect the interior door handle cable, snapping the plastic retainer back in place by hand or with needle-nose pliers.
• Align the top of the door panel with the window ledge and hook it over the edge.
• Push the panel straight down to seat it on the ledge.
• Once aligned, press around the edges of the panel to engage all clips; replace any broken clips with new ones by hand.

Step 14: Reinstall screws and trim pieces

• Install the armrest screw using a Phillips #2 screwdriver and tighten to about 5 N·m (44 in‑lb) with your torque wrench if possible.
• Install the screw behind the interior handle with the Phillips #2 screwdriver, also tightening to about 5 N·m (44 in‑lb).
• Snap the small trim cover back behind the interior handle by hand.
• Reconnect the window switch connector and press the switch panel back into place using your hands.

Step 15: Final electrical reconnection and window initialization

• Reconnect the battery negative terminal with a 10mm socket and tighten securely.
• Turn ignition to ON (engine off).
• For auto‑down/auto‑up reset on the driver window:
  • Fully lower the window using the switch and hold the switch down for 2–3 seconds after it reaches bottom.
  • Then fully raise the window and hold the switch up for 2–3 seconds after it reaches top.
• This teaches the switch the window limits

✅ After Repair

• Test the repaired window several times: full up, full down, and partial positions; listen for grinding, popping, or slowing.
• Operate the door lock, interior handle, and exterior handle to be sure the door opens and closes normally.
• Check all door switches (window, lock, mirror if equipped) for proper function.
• Drive on a short, quiet road and listen for new rattles or wind noise from the repaired door; gently press on the panel inside to locate any loose clips if needed.
• If you replaced both sides, repeat the function checks on each front door.
