How to Replace Wiper Blades
Replacing wiper blades on the Mercedes A-Class is straightforward and takes under 5 minutes:
Step 1: Lift the wiper arm away from the windscreen until it locks in the upright position. Place a cloth on the glass as protection.
Step 2: Press the Push Button release tab on the wiper connector and slide the old blade off the arm.
Step 3: Slide the new blade onto the arm until you hear it click securely into place.
Step 4: Gently lower the arm back to the windscreen. Repeat for the other side.
When to Replace Your Wipers
Replace your Mercedes A-Class wiper blades when you notice streaking, smearing, squeaking, or juddering. As a general rule, replace them every 12 months — UK weather conditions (frequent rain, frost, and sun exposure) degrade rubber faster than many drivers expect.
