🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the door trim panel

• Use a trim panel removal tool to pry off the switch bezel and trim covers.
• Use a Phillips screwdriver and 10mm socket to remove the screws in the armrest and lower door area.
• Carefully lift the door panel off the clips and unplug the switch connector.

Step 2: Remove the vapor barrier

• Peel back the door vapor barrier slowly.
• Use a trim panel removal tool if the adhesive is stuck.
• Keep the barrier clean so it can be reused or replaced.

Step 3: Secure the glass

• Use masking tape to hold the window glass fully up against the door frame.
• Apply tape from the outside of the glass, over the roof, and back down the inside.
• Use several strips for support.

Step 4: Disconnect the glass from the regulator

• Use an 8mm socket and ratchet to remove the glass-to-regulator bolts through the access holes.
• Slide the glass slightly by hand to free it from the regulator clamps.
• Leave the glass taped in place.

Step 5: Remove the old regulator

• Use a 10mm socket, ratchet, and extension bar to remove the regulator mounting bolts.
• Unplug the window motor connector if it is attached to the regulator assembly.
• Work the regulator out through the large service opening in the door.

Step 6: Install the new regulator

• Insert the new front window regulator assembly into the door opening.
• Start all mounting bolts by hand first.
• Install the glass into the regulator clamps and tighten the glass bolts.
• Torque to 8 Nm (71 in-lbs) for small glass/regulator fasteners unless your service data specifies otherwise.

Step 7: Reconnect and test the window

• Reconnect the window switch connector and battery.
• Cycle the window up and down with the switch.
• Make sure the glass moves smoothly and seats evenly at the top.
• Listen for cable rub or clicking.

Step 8: Reassemble the door
