Wipers Blades Do Not Park Notchback

Intermittent, park, and washer wipers are all low speed wiper motor functions controlled through the wiper relay integrated in the IP fuse block. During intermittent and wash operation the switch signals are inputs to the multifunction module integrated in the IP fuse block. The multifunction module controls the wiper relay through a low side drive control circuit and whenever the relay is energized ignition voltage will be supplied from the relay through the windshield wiper switch to the wiper motor low speed circuit. The wiper motor park switch is integrated in the wiper motor and is closed whenever the motor is out of the park position. Ignition voltage is supplied to the park switch and while the switch is closed the voltage will be supplied to the wiper relay through the park control circuit. Whenever the wiper relay is in the de-energized state, ignition voltage from the park control circuit will be supplied from the relay through the windshield wiper switch to the wiper motor low speed circuit until the park switch opens.

Description and Operation

Wiper/Washer System Description and Operation

Electrical Information Reference

1. Ignition ON, verify the low speed windshield wipers operate.

⇒	If the windshield wiper low speed function is inoperative, refer to Wipers Do Not Work on Low Speed.

2. Verify the intermittent windshield wipers operate.

⇒	If the windshield wiper intermittent function is inoperative, refer to Wipers Do Not Work on Intermittent.

1. Ignition OFF, disconnect the harness connector at the windshield wiper motor.
2. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 3 and ground.

⇒	If the test lamp does not illuminate, test the ignition circuit for an open high resistance.

3. Ignition OFF, test for less than 5 Ω between the park control circuit terminal 2 and the wiper motor low speed circuit terminal 5.

⇒	If greater than the specified range, test the park control circuit terminal 2 for an open/high resistance. If the circuit tests normal replace the IP fuse block.

4. If all circuits test normal replace the windshield wiper motor.
