Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 4.

Reconnect the connector and make these input tests at the connectors.

If any test indicates a problem, find and correct the cause, then recheck the system.

If all the input tests prove OK, go to step 5.

3	LT GRN/BLK	Ignition switch ON (II) and rear window wiper in parked position	Check for voltage to ground: There should be battery voltage.	Blown No. 11 (10 A) fuse in the driver's under-dash fuse/relay box Faulty rear window wiper motor An open in the wire
4	BLU/WHT	Ignition switch ON (II) and rear window wiper switch ON	Check for voltage to ground: There should be battery voltage.	Blown No. 11 (10 A) fuse in the driver's under-dash fuse/relay box Faulty wiper/washer switch An open in the wire
5	GRN/YEL	Ignition switch ON (II) and rear window washer switch ON	Check for voltage to ground: There should be battery voltage.

Disconnect the 8P connector, and make this test at the connector.

If the test indicates a problem, find and correct the cause, then recheck the system.

If the input test proves OK, the control unit must be faulty; replace it.
