Intermittent Operation
The wiper motor operates the wiper arms one time at low speed at a set interval of approximately 3 to 13 seconds. This feature is controlled by the wiper amplifier (INT SW) combined with wiper switch.
When the wiper switch is placed in the INT position, ground is supplied to wiper amplifier.
The desired interval time is input to wiper amplifier (INT VR) from wiper volume switch combined with wiper switch.
Then intermittent ground is supplied:
- to wiper motor terminal L
- from terminal 14 of wiper switch
- through wiper amplifier (OUTPUT).
The wiper motor operates at low speed at the desired interval.
