The center clip of the GLC wiper has a locking button that must be pressed to remove the wiper. After parking the vehicle, lift the middle part of the wiper arm by hand and press the clip to separate the wiper. Make sure the new wiper blades match the original model and reinstall them using the same method.

















Last time when my GLC300 wiper blades weren’t cleaning properly, I replaced them myself a few times—it was quite convenient. First, make sure to confirm the size; typically, the driver’s side is 26 inches, and the passenger side is 19 inches for this model, to avoid buying the wrong ones. Head to an auto parts store and pick a good brand of wiper blades, like Bosch, which are durable and easy to install. Before replacing, start the car to the ACC position without ignition, turn the wipers to the highest speed, and then turn off the power—the wipers will automatically stop in the middle of the windshield for easier operation. Then, gently lift the wiper arm by hand, but don’t let go too quickly, or it might snap back and damage the glass. Locate the release button on the wiper head, press it, and remove the old blade. Align the new blade and slide it in until you hear a click, indicating it’s secured. Test the wipers to ensure smooth operation, and you’re done. It’s recommended to replace them every six months for safer driving in the rain. Pay attention to fogging or water streaks on the wipers—replace them immediately if noticed. DIY replacement saves on repair shop costs and is simple and cost-effective. Choose a shady spot to do the job, avoid rainy days, and prioritize safety.

I've been driving a GLC300 for several years at my age, and I've never asked for help when replacing the wiper blades. It's quite simple. First, prepare the new wiper blades—remember, the sizes are 26 and 19 inches. Enter maintenance mode: start the engine to ACC state, and after a while, the wipers will stop in the middle position. Gently lift the wiper arm, but don't use too much force. To remove the old blade, press the small button on the wiper head to release it, then take it off. For the new one, align it with the slot and push until it locks into place. After installation, test the wipers to ensure they work properly. I prefer rubber blades for their cost-effectiveness. Check them during rainy days if visibility is poor—don’t wait until they rust or get damaged. Doing it myself saves tens of dollars in labor each time and extends the wipers' lifespan. Tackling small tasks like this is both practical and good exercise. Regular maintenance, about every six months, keeps the car running smoothly. Always work in a dry garage to prevent accidents.

Replacing the wiper blades on my own GLC300, I learned as a beginner. Basically, it can be done in three simple steps: First, purchase the correct size wiper blades, 26 inches for the driver side and 19 inches for the passenger side will do. Second, with the car turned on but not started, operate the wipers to the high position and then turn them off, they will stop in the middle of the windshield. Then carefully lift the wiper arm up, being careful not to touch the car paint. Third, press the wiper connector button to remove the old blade, insert the new one and snap it into place. Choose brands like PIAA for quiet and durable performance. Be gentle during operation as plastic parts are fragile. Check regularly and replace every six months to avoid accidents due to poor visibility in rainy weather. After replacement, test for smooth wiping to ensure everything is fine. It's not difficult and saves the hassle and expense of hiring a mechanic. Do it safely in the garage.

After driving the GLC300 for a long time, I realized that replacing wiper blades is a small expense with big benefits. First, confirm the correct sizes, usually 26 and 19 inches.
