WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

Use a Starter, Alternator, Battery, Regulator and Electrical (SABRE) tester to test the wiper motor on the vehicle.

To test the wiper motor, disconnect the windshield wiper mounting arm and pivot shaft from the windshield wiper motor; refer to WIPER MOTOR .

Disconnect the wiper motor. Connect the (1) green lead from the (2) SABRE tester to the battery negative (-) post. Connect the (3) red lead from the SABRE to the wiper motor (4) common brush terminal (terminal 4).

Test the low-speed mode by connecting a (5) cable from the battery positive (+) post to the (6) low-speed brush terminal (terminal 5) and measure the current draw. If the current draw is greater than 3.5 amperes, install a new windshield wiper motor.

Test the high-speed mode by connecting a cable from the battery positive (+) post to the (7) high-speed brush terminal (terminal 3) and measure the current draw. If the current draw is greater than 5.5 amperes, install a new wiper motor.
