Installation Guide for Mercedes Benz M-Class (2012-2015 (W166))
Fitting beam wiper blades to your Mercedes Benz M-Class takes about 60 seconds per blade. No tools required.
-
1
Lift the wiper arm
Pull the wiper arm away from the windscreen until it locks in the upright service position. Do this one arm at a time to avoid the arm snapping back onto the glass.
-
2
Release the old blade
Most Mercedes Benz M-Class models use a hook connector. Press the small tab on the underside of the blade, then slide the blade down the arm and off the hook.
-
3
Fit the new beam blade
Match the 26 inches / 650 mm blade to the driver side and the 24 inches / 600 mm blade to the passenger side. Slide the new blade onto the arm hook until you hear it click into place.
-
4
Lower and test
Gently lower the arm back onto the glass. Run the wipers once with a light water spray to confirm smooth, chatter-free contact across the full sweep.
-
5
Rear wiper
Your Mercedes Benz M-Class also has a rear wiper (12 inches / 300 mm). Rear blades typically pull straight off the arm — check the connector type before ordering.

Beam vs Traditional Blades for Mercedes Benz M-Class
Modern Mercedes Benz models ship from the factory with beam-style wiper blades for a reason — here's how they compare to the older frame-and-hinge design.
| Beam Blade (recommended) | Traditional Frame Blade | |
|---|---|---|
| Windscreen contact | Continuous spring-steel pressure across the full length | Pressure at 4–8 hinge points only |
| Highway performance | Aerofoil spoiler holds the blade down at speed | Lifts off the glass above ~90 km/h |
| Cold-weather use | Sealed frame — no hinges to ice up | Exposed joints can freeze and streak |
| Typical lifespan | 12–18 months | 6–9 months |
| Look on a modern Mercedes Benz | Low-profile, factory-correct | Bulky, dated silhouette |
The blades listed for your M-Class above are premium beam-style — the same design Mercedes Benz fits at the factory. Scroll up to order the exact-fit set.
