WIPERS/WASHER SYSTEMS

Caution : Disconnect the negative battery cable before removing or installing any electrical unit or when a tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless otherwise noted.

DESCRIPTION AND OPERATION

WINDSHIELD WIPER SYSTEM

The windshield wiper system consists of a wiper motor, a linkage, a wiper arm and a blade, and a wiper/washer switch.
The windshield wiper circuit incorporates a self-parking device which consists of a worm gear and a cam plate in order to keep the circuit engaged temporarily when the switch is turned off. The wiper system is driven by a permanent magnet-type motor. The windshield wiper motor is mounted on the dash panel and is directly connected to the windshield wiper linkage. The windshield wiper motor has two speeds, LO and HI, and also has intermittent wiper capability. The wiper switch is an integral part of the wiper/washer switch. Windshield wiper operation is actuated through the lever on the right side of the steering column.

WINDSHIELD WASHER SYSTEM

The windshield washer system is equipped with a washer fluid reservoir, a washer fluid pump, hoses, nozzles, and a wiper/washer switch. The windshield washer reservoir is mounted behind the front left wheel well splash shield. Attached to the reservoir is a washer pump, which pumps fluid through the hoses to the two nozzles mounted on the hood. The washer switch is an integral part of the wiper/washer switch. Windshield washer operation is actuated through the lever on the right side of the steering column.

REAR WINDOW WIPER/WASHER SYSTEM

The rear window wiper system consists of a wiper motor, a wiper arm, and a blade. The rear window wiper motor is located inside the hatchback/tailgate door and is directly connected to the rear window wiper. The rear window washer system is equipped with a separate washer fluid pump and hose. The hatchback has a hatch-mounted rear window washer nozzle and on the wagon, the washer nozzle is incorporated into the rear wiper motor. The rear window washer reservoir is mounted behind the front left wheel well splash shield. Attached to the reservoir is a washer pump, which pumps fluid through a hose to the rear washer nozzle.

RAIN SENSING SYSTEM (EUROPE ONLY)

The sensor is mounted inside of the windshield, near the rearview mirror. The sensor projects infrared light into the windshield at a 45-degree angle. If the glass is dry, most of the light is reflected back into the sensor by the front of the windshield. If water droplets are on the glass, they reflect the light makes it back into the sensor. The electronics and software in the sensor turn on the wipers when the amount of light reflected onto the sensor decreases to a preset level. When the wiper is turned AUTO, the unit can operate the wipers at any speed. The software sets the speed of the wipers based on how fast the moisture builds up between wipers. The system adjusts the speed as often as necessary to match with the rate of moisture accumulation.
