Abstract
A pump mounted in a housing is fluidically coupled to a vehicle windshield washer fluid reservoir. At least one outlet is carried on the pump housing for discharging fluid pumped from the reservoir. A fluid level sensor is mounted in the housing and has a sensing end projecting into the reservoir. The sensor includes a pair of spaced sensors having the sensing ends exposed to fluid within the reservoir. The sensor has a labyrinth shape adjacent to the sensing ends.
