Wiper System Inspection

WINDSHIELD WIPER MOTOR CHECK

Inspect the windshield wiper motor by removing the harness connector with the motor attached to the vehicle.

WIPER MOTOR AT LOW OR HIGH SPEED OPERATION







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 as shown in the illustration (A).
2. Run the windshield wiper motor at low speed, then disconnect the battery in the middle of the motor turning and check to see that the motor stops.
3. As shown in the illustration (B), connect the terminals of the windshield wiper motor connectors.
4. Check to see that the windshield wiper motor runs at low speed and then stops at the automatic stop position.

WINDSHIELD WIPER SWITCH CHECK

Windshield Wiper Switch Check:

Check continuity between the switch terminals.

WINDSHIELD INTERMITTENT WIPER INTERVAL CHECK







Check that the resistance varies between 0 and 1 kOhm when the windshield intermittent interval is turned from FAST to SLOW by after measuring resistance between connector terminals 27 and 28 at the column switch.
