Wiper Motor Circuit
- Disconnect 6-pin wiper motor connector. Turn ignition switch to ON position. Measure voltage between terminal No. 6 (Blue wire) and ground. See WIRING DIAGRAMS . If battery voltage is present, go to next step. If battery voltage is not present, check wire harness, connectors and 20-amp WIPER fuse located in instrument panel junction block, behind left kick panel. Repair or replace as necessary. Retest system operation.
- Measure voltage between specified terminals and ground with wiper/washer switch in specified position. See WIPER MOTOR CIRCUIT VOLTAGE table. See WIRING DIAGRAMS . If battery voltage is as specified, go to next step. If battery voltage is not as specified, check wire harness, connectors and 20-amp WIPER fuse located in instrument panel junction block, behind left kick panel. Repair or replace as necessary. Retest system operation.WIPER MOTOR CIRCUIT VOLTAGE
Terminal No. Switch Position (1) Voltage 2 & Ground OFF Or INT, LO Zero 2 & Ground HI Or MIST Battery 3 & Ground OFF Or INT, HI Zero 3 & Ground LOW Or MIST Battery (1) With ignition switch in ON position. - Turn ignition switch to OFF position. Check continuity between terminal No. 1 (White/Black wire) and ground. If continuity exists, check wiper motor. See WIPER MOTOR under COMPONENT TESTS. Replace wiper motor as necessary. Retest system operation. If continuity does not exist, repair open in White/Black wire between wiper motor and ground connection. Retest system operation.
