Washer Operation

When the switch is turned to "ON", battery, voltage is applied to terminal "D" of the wiper motor assembly through CKT 113. The washer switch also applies voltage to terminal "A" which turns "ON" the washer pump through CKTs 94 and 228. The wiper motor has voltage applied through the low speed relay and operates at low speed for 2 to 4 wipes.
When the washer switch is held "ON", the wiper motor circuit board will keep the washer pump ON" only as long as the washer switch is held "ON".
If the wipers had been in "DELAY", "LO" or "HI", they would return to that operation after the wash cycle. If in "OFF", they then return to park position after 2 to 4 wipes.
