Washer Operation

With the ignition switch in the ACC or ON position, power is supplied:
^ through 2 A fuse (No. 7, located in the fuse block)
^ to washer motor terminal (1).
When the lever is pulled to the WASH position, ground is supplied:
^ to washer motor terminal (2), and
^ to wiper amplifier terminal (7) (with intermittent wipers)
^ from terminal (5) of the wiper switch
^ through terminal (6) of the wiper switch, and
^ through body grounds (M49), (M105) and (M160).
With power and ground supplied, the washer motor operates.
The wiper motor operates twice at low speed for approximately 3 seconds to clean the windshield. This feature is controlled by the wiper amplifier in the same manner as the intermittent operation.
