A windshield washer control for a vehicle is responsive to vehicle speed to vary the speed of an electric motor driven pump so as to vary the pump pressure with vehicle speed and thus counteract the downward dislocating effect, increasing with vehicle speed, of air rushing over the windshield, whereby the cleaning fluid is applied to a predetermined target area of the windshield regardless of varying vehicle speed. In addition, the pump may be activated for a time varying inversely with vehicle speed to counteract the variation of volume flow with varying pump pressure and thus cause a substantially constant volume of cleaning fluid to be applied to the windshield for each activation of the pump.
