Checking the Windshield Wiper Switch

Using an ohmmeter, check the conductivity between the connector contacts at different positions of the windshield wiper switch (Fig. 17.68).

Checking the windshield wiper motor

The windshield wiper motor must be installed in the vehicle and the electrical harness connector must be disconnected from the motor.
Using additional wires, connect the battery terminals to the engine connector terminals as shown in Figure 17.69 (A), and check the operation of the windshield wiper at low and high speeds.
Using additional wires, connect the battery terminals to the engine connector terminals as shown in Figure 17.69 (B) and let the engine run at low speed. When the engine is running, disconnect the positive battery terminal wire and stop the engine.
Using additional wires, connect the battery terminals to the engine connector contacts, and also short-circuit connector contacts 1 and 4 as shown in Figure 17.69 (B), and make sure that the engine stops in its original position.

Checking the windshield washer motor

When checking, the tank must be installed in the car and filled with liquid.
Using additional wires, connect the positive terminal of the battery to contact 2 of the connector and the negative terminal to contact 1 of the connector, while the liquid should spray onto the windshield (Fig. 17.70).

Checking the fluid level sensor in the washer reservoir

Remove the washer fluid level sensor from the reservoir.
Connect an ohmmeter to the contacts of the washer fluid level sensor connector in the washer reservoir (Fig. 17.71).

Make sure that when the float moves down, the circuit is closed, and when the float moves up, the circuit is opened.

Checking the position of the windshield sprayers
By moving the sprayers in their sockets, achieve correct spraying of liquid jets onto the windshield, as shown in Figure 17.72.
