Mercedes-Benz SL600 Washer Fluid Level Switch Replacement at your home or office.

What is the Washer Fluid Level Switch all about?

Many vehicles are equipped with a washer fluid level switch or sensor that illuminates a light on the dash when the fluid is low in the washer fluid reservoir. The switch is located at the bottom of the washer fluid reservoir and is a simple resistance switch. When the sensor no longer recognizes the correct electrical resistance because there isn’t washer fluid touching the sensor, it sends a signal for the low washer fluid level warning to illuminate. To prevent the warning from coming on when the washer fluid is sloshing in the reservoir, there is typically a one minute delay before the warning illuminates. If the washer fluid level switch is not working as it should, the low washer fluid level warning will not illuminate before the reservoir is empty or will be illuminated all the time, even with a full reservoir.
