Abstract
A wiper control apparatus includes a main relay switch for passing the voltage received from a power supply to make the wiper control apparatus operable, an ignition switch for passing the voltage from the power supply to make the vehicle operable, and control means for controlling the ON/OFF operation of the main relay switch. The control means operates in response to the conductive state of the ignition switch to render the main relay switch conductive. After a predetermined time in response to a cut-off state of the ignition switch, the control means renders the main relay switch non-conductive. The predetermined time allows the wiper blade to move down to a predetermined park position of a windshield after the ignition switch is turned off.
