Brief description


Saab 9-5 is equipped with a washer and wiper system for cleaning the windscreen and headlamps.

The system is controlled by the steering column stalk switch to the right of the steering wheel as well as the rain sensor and the DICE (see DICE).

The wiper system without rain sensor is controlled by the steering column stalk switch to the right of the steering wheel and the DICE (see DICE).

The washer and wiper system comprises:

Rain sensor

The rain sensor is located on the inside of the windscreen in front of the rearview mirror. The rain sensor is a control module with its own logic. The control module is activated by setting the wiper stalk switch to the automatic position. The rain sensor detects whether there is water or snow on the windscreen and activates the windscreen wipers accordingly. A light sensor measures the exterior light intensity in order to adjust the sensitivity of the rain sensor to the surrounding light level.

Windscreen wipers with rain sensor

The windscreen wiper assembly is located under the cover beneath the windscreen. It comprises a motor, arm assembly and two wiper arms with wiper blades. The wipers are controlled by the rain sensor and two wiper relays.

The windscreen wipers have two speeds (high/low) and an automatic position. When in the automatic position, the sensitivity of the rain sensor can be controlled with a switch on the control stalk.

Windscreen wipers without rain sensor

The windscreen wiper assembly is located under the cover beneath the windscreen. It comprises a motor, arm assembly and two wiper arms with wiper blades. The wipers are controlled by the DICE and an intermittent wiper relay.

The windscreen wipers have two speeds (high/low) and one intermittent wiper position, the frequency of which can be regulated to intervals of between 2 and 15 seconds by a control on the control switch.

Rear window wiper

The rear window wiper is located on the tailgate and comprises a motor and a wiper arm with wiper blade. The washer jets are located by the wiper arm mounting on the tailgate and direct the washer fluid upwards on each side of the wiper blade.

The function is controlled by DICE. The rear window wiper has an intermittent position. The interval between wiper strokes cannot be adjusted.

Headlamp wipers

Each headlamp has a headlamp wiper beneath it. The wipers act when the windscreen washer is activated.

Washer assembly

The washer assembly is located at the front of the left-hand front wing. It consists of a reservoir with two pumps and a level monitor. There are hoses leading to the nozzles on the bonnet, headlamp wiper arms and the rear wiper arm mounting. See:
