Abstract
A windshield wiper control system has operations controlled by single touch actuators. A first such actuator provides for initiation of wiper operation in low speed with the first actuation and alternate high and low speed operation with additional actuations. A second such actuator stops wiper operation and, if actuated while the wiper is not running, initiates a single wipe of the wiper. A further actuator may be provided for initiation of either programmed or operator controlled wash operation, depending on the length of actuation. A final actuator may be provided for two touch intermittent wiper operation, in which the operator sets the delay time by two consecutive touches. Variations are described for either depressed park or non-depressed park systems.
