Description
Restore the full functionality of your Mercedes‑Benz washer system with this genuine washer pump motor, part number 210 869 09 21. This OEM‑replacement unit ensures reliable operation of the windshield (and in some cases rear) washer system, supplying fluid when you activate the wiper‑washer switch.
Manufactured to Mercedes factory specifications, the pump delivers the correct flow and pressure to the washer jets, enabling effective cleaning of your windshield for improved visibility and safety.
