Connect a jumper wire from the battery negative post to the low speed terminal of the windshield wiper motor and read the current draw. Move the jumper wire from the low-speed terminal to the high-speed terminal and read the high-speed current draw. In either case, the current draw should not exceed 3.5 amperes. if the current draw does exceed 3.5 amperes, check the output arm and windlatch mechanism for binding or damage before replacing the windshield wiper motor.
