The windshield and rear window wipers do not work satisfactorily. Windshield wipers do not work or work very slowly

• The wiper blades are rubbing against the glass, or the drive rod is sticking (Chapters 1 and 12).
• The fuse has blown (Chapter 12).
• The cable or cable plugs are broken, disconnected or torn off (Chapter 12).
• Relay faulty (Chapter 12).

The wiper blades cover too much or too little area of the glass

• The windshield wiper arms are not correctly positioned on the pivot points (Chapter 12).
• The windshield wiper drive is excessively worn (Chapter 12).
• The windshield wiper motor or drive mounts have become loose (Chapter 12).

The windshield wipers cannot clean the glass effectively

• The rubber pads of the windshield wipers are worn out or damaged (Chapter 1).
• The return springs are broken or the wiper arm pivots are jammed (Chapter 12).
• The effectiveness of the used washer additive is not sufficient to remove road dust (Chapter 1).

The windshield and rear window washers do not work or work poorly. One or more washer jets are not working

• The washer jet is clogged (Chapter 12).
• The fluid supply hose is disconnected, kinked or pinched (Chapter 12).
• Not enough fluid in the washer reservoir (Chapter 1).

The washer pump works for a while and only then does the liquid start to flow out of the nozzles

• The one-way valve of the fluid supply hose is faulty (Chapter 12).

The washer pump is not working

• Broken, disconnected or torn wires or wire plugs (Chapter 12).
• The fuse has blown (Chapter 12).
• The washer switch is faulty (Chapter 12).
