Intermittent (J)

WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

There is a built-in mechanically controlled connector (31B) in the wiper motor that receives power irrespective of the switch's (61) position. As a result, the intermittent function only requires a start pulse from DICE to become active.

When the switch is placed in position (J), power is supplied from pin 10 in switch (61) to pin 21 in DICE (628). The control module emits a start pulse from pin 58 which activates the relay (83). Input voltage is supplied to pin 9 in the switch (61), with output voltage at pin 8. The power supplied to pin 3 in the motor (62F) is equivalent to the low-speed position.

The potentiometer (618) in switch (61) is connected to DICE (628) at pins 55 and 33. Resistance varies between 0 and 1 kohm. The lower value is equivalent to the short interval (2 seconds) and the higher value to the long interval (15 seconds).

The switch (31B) controls the voltage so that the wiper motor always returns to the parking position after the current from the switch has been cut off. When the wiper motor reaches the parking position, the mechanically operated switch cuts off the current and the motor stops until DICE sends the next start pulse.
