Abstract
A scrubber assembly (14) for a windshield wiper (10) having a wiper arm (12) includes a scrubber housing (22) attached to the wiper arm. The scrubber housing (22) has an interior volume (66) and at least one opening (58). A rod (68) is at least partially disposed in the interior volume (66) and is displaceable from a first position to a second position. A brush assembly (42) is attached to the rod (68) with at least one flexible connecting member (76) that extends through the at least one opening (58) to the brush assembly. When the rod (68) is in the first position, a first portion of the flexible connecting member (76) protrudes from the opening (58), and when the rod is displaced to the second position, a second portion of the flexible connecting member that is larger than the first portion protrudes from the opening.
