Test F: Wipers Will Not Park Properly
WARNING: This page is about a different car, the 1997 Lincoln Mark VIII. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect wiper motor connector. Turn ignition on. Measure voltage between Black wire and White/Black wire at wiper motor connector. If battery voltage exists, go to step 3). If battery voltage does not exist, go to next step.
- Turn ignition off. Measure resistance of Black wire between wiper motor connector and ground. If resistance is 5 ohms or less, repair open in White/Black wire. If resistance is greater than 5 ohms, repair open in Black wire. After repair, retest system.
- Measure resistance between Black/Pink wire and Dark Blue/Orange wire and between Yellow/Red wire and Red wire terminals at wiper motor connector. If resistance is greater than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, check wiper linkage for binding. Repair as necessary. If linkage is okay, replace wiper motor and retest system.
- Disconnect IWWM connector. Measure resistance of Red wire between IWWM connector and wiper motor connector. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Red wire. Retest system.
- Measure resistance of Black/Pink wire between IWWM connector and wiper motor connector. If resistance is 5 ohms or less, replace IWWM. If resistance is greater than 5 ohms, repair open in Black/ Pink wire. After repair, retest system.
