Short-handle Phillips screwdriver, short-handle flat-head screwdriver, long-handle Phillips screwdriver, pliers, socket wrench, tape, rust penetrant, grease, and door panel trim clips. Remove the center console switch. Use a long-handle flat-head screwdriver with a towel padding to pry it open from the top end (the side with the rearview mirror control button). Pry open the door handle cover and remove the two Phillips screws inside. Remove the single Phillips screw inside the handle. Push the handle box forward. Apply grease on the tracks to prevent rust and extend service life. Install the new regulator inside the door panel, connect the wiring harness, and expose the glass bracket installation position.

Last time I replaced the left front door window regulator on my Excelle by myself, it took some effort but was worth it. First, prepare the tools: a Phillips screwdriver, a pry bar, and a 10mm socket wrench. Park the car securely, and you'll find hidden screws inside the door panel. Remove them carefully with the pry bar to take off the interior trim panel, being cautious not to damage the plastic clips. Disconnect the power to avoid short circuits by removing the negative terminal from the battery. Loosen the bolts securing the old regulator, gently lift out the regulator and glass bracket, and align the new part in place. Remember to check if the glass is level, and ensure all clips are securely fastened when reassembling the interior trim panel. Test the window operation several times to ensure smooth movement—the entire process takes about 60 to 90 minutes. For those attempting this, it's best to consult the vehicle's repair manual for detailed references. If unsure, it's advisable to seek professional help to prevent misalignment that could cause the window to jam.

For those who frequently tinker with cars, replacing the left front door window regulator is a practical task. For the Excelle, ensure sufficient space inside the car before starting. I learned from online tutorials: use a screwdriver to remove screws near the door handle and interior panel, then gently pry open the panel to expose the regulator mechanism. Handle the old parts carefully to prevent the glass from slipping and causing injury. Purchase a new regulator of the matching model, and after installation, test if the height adjustment is accurate. In terms of tools, a basic socket set is sufficient, and anti-static gloves with safety goggles are good to have on hand. The entire process emphasizes precision to avoid time-consuming repeated disassembly. After completion, lubricating the tracks can extend the lifespan. DIY enthusiasts can save a few hundred bucks, but it's best to have a friend assist on the first attempt.

I tried DIY replacing the left front window regulator on my Excelle. Briefly: first disconnect the battery to prevent risks, remove the car key. Unscrew the interior panel screws, gently pry off the panel using tools. Remove the old regulator, align and secure the new part. Reinstall the interior panel firmly, test if the window rolls smoothly. Wear gloves throughout, avoid sharp edges. Beginners should learn basics from videos first, or seek professionals to prevent door component deformation/damage. Simple job but safety first.
