Reservoir, Windshield Washer: Operation

The washer fluid reservoir provides a secure, on-vehicle storage location for a large reserve of washer fluid for operation of the front and rear washer systems. The washer reservoir filler neck provides a clearly marked and readily accessible point from which to add washer fluid to the reservoir.

The reversible front and rear washer pump/motor unit is located in a sump area near the bottom on the outboard side of the reservoir to be certain that washer fluid will be available to the pump as the fluid level in the reservoir becomes depleted. The front and rear washer pump/motor unit is mounted in the lowest position in the sump. The washer fluid level switch is mounted just above the sump area of the reservoir so that there will be adequate warning to the vehicle operator that the washer fluid level is low, before the front and rear washer systems will no longer operate.

On vehicles equipped with the headlamp washer system the reservoir features a second sump located rearward of and above the front and rear washer pump sump. This allows the front and rear washer systems to remain operational after the washer fluid level falls below the pump inlet for the headlamp washer pump.
