Wiper Motor: Testing and Inspection
INSPECTION1. INSPECT WINDSHIELD WIPER MOTOR ASSEMBLY
a. Check the LO operation.
1. Connect the positive (+) battery lead to terminal 5 (+1) of the connector, and the negative (-) battery lead to terminal 4 (E), and check that the motor operates at low speed (LO).
OK: Motor operates at low speed (LO).
If the result is not as specified, replace the motor assembly.
b. Check the HI operation.
1. Connect the positive (+) battery lead to terminal 3 (+2) of the connector, and the negative (-) battery lead to terminal 4 (E), and check that the motor operates at high speed (HI).
OK: Motor operates at high speed (HI).
If the result is not as specified, replace the motor assembly.
c. Check the automatic stop operation.
1. Connect the positive (+) battery lead to terminal 5 (+1) of the connector and the negative (-) battery lead to terminal 4 (E). With the motor operating at low speed (LO), disconnect terminal 5 (+1) to stop the wiper motor operation at any position other than the automatic stop position.
2. Using SST, connect terminals 1 (S) and 5 (+1). Then connect the positive (+) battery lead to terminal 2 (B) of the connector to restart the motor operation at low speed (LO).
