Wiper Motor: Testing and Inspection
WINDSHIELD WIPER MOTOR
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.
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 3).
Test the low-speed mode by connecting a (5) cable from the battery positive (+) post to the (6) low-speed brush terminal (terminal 2) 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 1) and measure the
current draw. If the current draw is greater than 5.5 amperes, install a new wiper motor.
