Except For Glass Hatch Model

With the ignition switch in the ACC or 0N position, power is supplied:
^ through 10 A fuse (No. (9), located in the fuse block)
^ to rear wiper amplifier terminal
^ to rear wiper motor terminal and
^ to rear washer motor terminal (1).
Ground is supplied:
^ to rear wiper amplifier terminal (6)and
^ to rear wiper switch terminal (3)
^ through body grounds (M5), (M78) and (M123).
Ground is also supplied:
^ to rear wiper motor terminal (2)
^ through body ground (B104).

WIPER OPERATI0N
When the rear wiper switch is in the WIPER position, ground is supplied:
^ to rear wiper amplifier terminal (1)
^ through rear wiper switch terminal (1).
An intermittent ground is then supplied:
^ to rear wiper motor terminal (3)
^ through rear wiper amplifier terminal (4)
^ to rear wiper amplifier terminal (6)
^ through body grounds (M5), (M78) and (M123).
With power and ground supplied, the rear wiper motor operates intermittently, with approximately a 15 seconds interval between cycles.

WASHER OPERATI0N
When the rear wiper switch is in the WASH position, ground is supplied:
^ to rear washer motor terminal (2) and
^ to rear wiper amplifier terminal (5)
^ through rear wiper switch terminal (2).
With power and ground supplied, the rear washer motor operates. The rear wiper amplifier then operates the rear wiper motor to clean the glass.

AUTO STOP OPERATI0N
When the rear wiper switch is placed in the 0FF position, the rear wiper motor will continue to operate until the rear wiper arm reaches the base of the glass.
When the rear wiper switch is placed in the 0FF position, the rear wiper amplifier no longer supplies a ground circuit to the rear wiper motor. The ground circuit is now routed through the rear wiper motor terminal (2). This allows the wiper motor to operate until the rear wiper arm reaches the base of the glass. The rear wiper motor ground is interrupted when the rear wiper arm reaches the base of the glass, and the rear wiper motor stops.
