1. INSPECT WINDSHIELD WIPER MOTOR ASSEMBLY

(a) Check the LO operation.





(1) Connect the positive (+) battery lead to terminal 1 (+1) of the connector, and the negative (-) battery lead to terminal 5 (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 4 (+2) of the connector, and the negative (-) battery lead to terminal 5 (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 1 (+1) of the connector and the negative (-) battery lead to terminal 5 (E). With the motor operating at low speed (LO), disconnect terminal 1 (+1) to stop the wiper motor operation at any position other than the automatic stop position.

(2) Using SST, connect terminals 3 (+S) and 1 (+1). Then connect the positive (+) battery lead to terminal 2 (B) of the connector to restart the motor operation at low speed (LO).
