1. Disconnect negative cable (-) at battery.
2. Disconnect combination switch lead wire coupler.
3. Use a circuit tester to check the continuity at each switch position. If any continuity is not obtained, replace switch.

Scheme 5

Scheme 6

1. As illustrated, use a 12 V battery to connect its (+) terminal to terminal "A", and its (-) terminal to Black lead wire. If motor rotates at a low revolution speed of 45 to 55 rpm, it is proper. For high speed check, connect battery (+) terminal to terminal "B", and its (-) terminal to Black lead wire. If motor rotates at a high revolution speed of 67 to 83 rpm, it is proper.
2. Testing Automatic Stop Action . Connect 12 V battery (+) terminal ("Red" lead wire (3)) to terminal "A" of wiper motor (2) and (-) terminal to "Black" lead wire (4) and let the motor turn. Disconnect terminal "A" from battery (1), and let the motor (2) stop. Connect terminal "A" and "D" with a jumper wire (5), and connect terminal "C" to battery (+) terminal. Observe the motor turns once again then stops at a given position. Repeat a through c several times and inspect if the motor stops at the given position every time.
