WARNING: This page is about a different car, the 1997 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Unplug wiper motor connector. Measure resistance of Black wire between wiper motor harness connector and ground. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open Black wire and retest system.
- Turn ignition on and wiper switch off. Check voltage between Dark Green wire and Black wire terminals of wiper motor harness connector. If battery voltage exists, go to next step. If battery voltage does not exist, repair open Dark Green wire or Black wire.
- Turn wiper switch off. At wiper motor harness connector, check resistance between Black/Pink wire and Dark Blue/Orange wire terminals, and between Yellow/Red wire and Black wire terminals. If resistance greater than 5 ohms, go to next step. If resistance is 5 ohms or less, inspect wiper linkage for damage. Repair as necessary. If linkage is okay, replace wiper motor.
- Unplug connector from Wiper Control Module (WCM) located at fuse block. Measure resistance of Black/Pink wire, Yellow/Red wire, Dark Blue/Orange wire and White wire between wiper motor and WCM. Repair open wire(s) as necessary. If wires are okay, replace WCM.
