Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Washer Fluid Indicator
The low washer fluid indicator is controlled by the instrument panel cluster (IPC) using an input from the washer fluid level switch. The washer fluid level signal circuit is supplied ignition voltage through a resistor then monitored within the instrument cluster. The washer fluid level switch is normally open so the instrument cluster detects ignition voltage on the washer fluid level signal circuit whenever the washer fluid level is not low. When the washer fluid level reaches the point where the driver should be informed that the washer fluid is low, the washer fluid level switch closes. When the washer fluid level switch is closed the washer fluid level signal circuit voltage is pulled low, and the instrument cluster illuminates the LOW WASHER FLUID indicator. In order to prevent the LOW WASHER FLUID indicator from flashing due to sloshing in the washer fluid container, the instrument cluster is programed with a 1 minute delay before changing states of the LOW WASHER FLUID indicator during an ignition cycle.
