摘要

The washer has an electric heater element inside pressurised container for the washer fluid. The washer jet outlets are sealed by a dosing needle acting as a non return spring valve. The heater is operated from the vehicle ignition and ensures that improved cleaning action is obtained. It also reduces the otherwise thermal shock when cold fluid is sprayed onto hot halogen lamps.
