WARNING: This page is about a different car, the 1997 Mercury Tracer and 1997 Ford Escort. However, it is still accessible from the selected car via links, so may be relevant.
- Check WIPER fuse (20-amp) in instrument panel fuse block. If fuse is blown, inspect Blue wire between fuse block and wiper switch, and between fuse block and wiper motor for short to ground. Repair Blue wire as necessary. If wire is okay, replace fuse and go to next step.
- Turn ignition off. Disconnect wiper motor connector. Turn ignition on. Measure voltage between ground and wiper motor harness connector terminal No. 2 (Blue wire). See Fig 1 . If battery voltage is present, go to next step. If battery voltage is not present, repair Blue wire between wiper motor harness connector and fuse block. See WIRING DIAGRAMS .
- Turn ignition off. Measure resistance between ground and wiper motor harness connector terminal No. 3 (Black wire). See Fig 1 . If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair Black wire between wiper motor harness connector and ground. See WIRING DIAGRAMS .
- Disconnect wiper/washer switch 6-pin connector. Turn ignition on. Measure voltage between ground and wiper/washer switch connector terminal No. 3 (Blue wire). See Fig 2 . If battery voltage is present, go to next step. If battery voltage is not present, repair Blue wire between wiper/washer switch connector and fuse block. See WIRING DIAGRAMS .
- Test wiper/washer switch. See WIPER/WASHER SWITCH under COMPONENT TESTING. Replace switch as necessary. If switch is okay, test wiper motor. See WIPER MOTOR under COMPONENT TESTING. Replace wiper motor as necessary.
