Lincoln Navigator rear windshield wiper motor causing battery drain issue on Lincoln Navigator

Some Lincoln Navigator owners report experiencing battery drain issues potentially linked to the rear windshield wiper motor. They note that a battery drain while the vehicle is not running may indicate a parasitic power loss or a faulty battery. Additionally, if the battery depletes while driving, it could suggest a problem with the vehicle's alternator. Some owners have identified that a faulty electronic park brake (EPB) switch with an internal short may cause the anti-lock brake system module to activate, which can lead to the controller area network (CAN) system waking up and draining the battery. It is also reported that checking the breaker in the rear window wiper motor can help prevent further battery drain, and if the rear windshield wiper motor's breaker keeps resetting itself, it may contribute to the ongoing battery drain issue. Addressing these potential causes can assist owners in effectively troubleshooting and resolving the battery drain problem.
