Some customers may complain that the frequency of replenishing the window washer liquid is higher than expected, or they may complain of leakage at or around the washer motor (1). This is caused by a crack that may occur at the joint section of the washer motor housing due to an inappropriate assembly process. To eliminate this concern, the design of the washer motor has been modified to not have a joint section.
