Hi photog7,

The delay function is handled by a series of resistors in the wiper/washer switch. The resistance between terminals A6 and D3 of the switch (the terminals that correspond to the white and light blue wires of the connector) should vary from 39 k-ohms to 680 k-ohms, depending on the position of the switch.
