Nissan's 240SX S13 is equipped with a 2-speed wiper system with time delay feature. Some models are equipped with a rear wiper/washer system.

WIPER MOTOR

All wiper motors include an integral park switch inside the motor housing. The motor cover can be removed and the switch adjusted if wipers do not park correctly. Some models have an externally mounted circuit breaker to protect the wiper motor.

WIPER AMPLIFIER

All Maxima, Stanza, 240SX and 300ZX models have a Time Control Unit (TCU) which controls the delayed wiper cycle. This unit also operates the clock, turn and hazard flashers, seat belt chimes and other timed delayed circuits.

WASHER

A check valve is located in washer line between reservoir tank and nozzle. If removed, install valve with arrow toward nozzle. All models have windshield washer systems. A separate pump is used for the rear washer. On all models a common reservoir is used for both washer systems.

WIPER ARM ADJUSTMENT

1. Prior to installing wiper arm, turn wiper motor switch ON then OFF (Auto Stop). Install wiper arm but do not tighten nut. Set blade down on glass.
2. Set blade so that centerline of wiper blade is at specified distance from edge of glass in the STOP position (horizontal stop wipers). On vertical stop wipers, the distance is measured from centerline of wiper blade to edge of black print on glass. Tighten wiper arm nut.
3. Operate washer motor to spray washer fluid on glass. Turn wiper switch ON to operate wiper motor. Turn wiper switch OFF. Ensure proper clearance is maintained.

WIPER AMPLIFIER TESTING

1. Disconnect and remove amplifier from vehicle or position so test leads, battery and test light can be connected to amplifier terminals. Use care to prevent improper connections since amplifier can be damaged.
2. Connect test leads and test light as shown to battery and terminals of amplifier.
Leaving test lead from terminal No. 6 for last, connect test lead to battery ground. If test light comes on, amplifier is normal. If not, replace amplifier.
