Abstract
A window washer control system and method administers fluid intermittently to a window based on an intermittent setting. A washer switch includes a plurality of frequency settings for varying a time interval between fluid administering events. The fluid level in a washer fluid reservoir is monitored to ensure a predetermined level. If the fluid level is below a predetermined level, control prevents intermittent washer administration and allows only manual activation.
