Follow these steps carefully
One catalog lists the rear at 260mm (about 10 inches) instead of 12 — measure your old rear blade and match it, but 12 inches is the majority answer.
26/19/12 — I write the sizes on my phone before going to the store. The rear 12-inch is the one everyone forgets.
The B-Class parks its blades below the hood's trailing edge. Do not try to fold the arms out from the parked position; the hood lip traps them and the pinch-tab arms bend if forced.
The 15-second window after ignition-off catches everyone the first time. I just keep trying until the arms actually stay up.
Squeeze both tabs inward with your thumb and forefinger and slide the blade downward off the arm. The pinch-tab release feels different from a hook — there is no tab to press on the underside, the squeeze.
Hold the new 26-inch blade's pinch-tab connector up to the arm's tongue and slide it upward until both side tabs click outward into their locked position — you will feel and hear the double click.
The passenger side uses the identical pinch-tab release: squeeze both side tabs, slide the old blade down and off. The 19-inch length is easy to confuse with a 20, so verify the box label — a 20-inch blade can strike the A-pillar trim on this car. While the arm is folded out, wipe the cowl area beneath the parked blades; the B-Class's deep cowl tray funnels leaves directly onto the blade rubber. Snap the 19-inch blade on until both tabs click, tug to confirm, and fold the arm down gently.
The rear wiper sits at the base of the liftgate glass under a small plastic cover. Flip the cover open at the arm's base and lift the short rear arm away from the glass — it will not fold out far, which is normal. Study the old blade's connector before removing it, then release it the same way and mount the new 12-inch blade (or the 260mm/10-inch size if that is what your old blade measures — match the old blade, not the catalog, if they disagree). Confirm the new blade sits flat on the glass and lower the arm gently.
Close the hood, switch the ignition on, and flick the stalk to bring the front wipers out of the service position — they will park themselves. Replace blades every 6 to 12 months.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
