How to replace the wiper blades on a Mercedes-Benz CLA?

First, prepare the necessary tools for removing the wiper blades: a flat-head screwdriver, a small ratchet, and a 13mm socket. Open the car's front hood, take out the flat-head screwdriver, and use it to pry off the small black cover of the wiper blade. After removing the small black cover, you will see the nut securing the wiper blade. Take out the small ratchet with the 13mm socket and remove this nut. Once the nut is removed, set it aside safely. Fold the wiper blade slightly by hand, hold it firmly, and shake it repeatedly until it loosens. At this point, you can remove the wiper blade. The process is the same for both left and right wiper blades. To install new wiper blades, follow the steps in reverse order.
Last time I replaced the wiper blades on my Mercedes-Benz CLA, it was quite straightforward. First, turn the car key to the ACC position without starting the engine. Then press the wiper button and lift it upward slightly, which automatically moves the wiper arms to the maintenance position—this step is crucial to avoid scratching the glass. Next, press the release button or tab at the bottom of the old wiper blade (usually a small button or latch), gently push to release, and slide out the old blade. Take out the new wiper blades you bought, ensuring they match the CLA model—Bosch is a good brand. Align them with the slot on the wiper arm, give a gentle push until they click into place, and listen for the 'click' sound. Finally, turn off maintenance mode, activate the wipers to test the spray and check if they wipe cleanly. It took me about 20 minutes to finish, saving the cost of going to a shop. I recommend checking them every six months—if there are large streaks or unusual noises, it’s time to replace them. Safe driving in the rain is the top priority.
