ABSTRACT:
A wiper assembly 30 for a rear view mirror 14 of a vehicle 22 that is automatically activated by a moisture sensor 60 attached to the exterior surface of a housing 12. The housing 12 is attached to the vehicle 22 by a mounting bracket 18 that includes an arm 20 interconnecting the vehicle 22 and the housing 12. The bracket arm 20 has an interior passage 21 that receives electrical wiring 50 that electrically connects a power source in the vehicle 22 to an electric motor 40 that drives the wiper assembly 30. A rack 44 and pinion 42 structure, in conjunction with motor reversing limit switches 48 provides for reciprocating movement of a wiper blade 36 across the reflective surface 16 of the mirror 14. An override switch 70 is located in the vehicle 22 so that the driver may selectively override the automatic activation of the wiper.
