Connect the battery to the windshield wiper motor to inspect the operation of motor rotation in low or high speed.

WIPER MOTOR AT STOP POSITION OPERATION






1. Connect the battery to the windshield wiper motor to rotate the motor in a low speed as shown in the illustration (A) and disconnect the battery during rotation to stop the motor.
2. Connect between the terminals and the battery as shown in the illustration (B) and confirm whether the motor stops at the automatic stop position after rotating in a low speed.

WINDSHIELD WIPER AND WINDSHIELD WASHER SWITCH CHECK






Check continuity between the switch terminals.

WINDSHIELD INTERMITTENT WIPER VOLUME CHECK






Check that the resistance varies between 0 and 1 k ohm when the windshield intermittent volume is turned from FAST to SLOW after measuring resistance between connector terminals 3 and 6 at the column switch.
