Each switch is precisely engineered for a perfect fit and seamless integration with your vehicle’s electrical systems, ensuring smooth, dependable operation and long-term reliability.

What Do Rear Wiper Switches Do?

Rear wiper switches are mounted on the steering column or dashboard and serve as the driver’s interface for rear window cleaning. They allow you to:

Activate and control the rear wiper motor for clear rear visibility. Engage the rear washer system to remove dirt, rain, or salt residue. Adjust wiper speed or intermittent settings (depending on model). Integrate with front wiper and lighting systems for coordinated control.

A properly functioning switch ensures you can maintain a clean rear window at all times — improving visibility and overall safety.

Why Do Rear Wiper Switches Fail?

Over time, wiper switches experience both electrical and mechanical wear, especially with regular use or exposure to environmental conditions. Common causes of failure include:

• Worn or oxidised electrical contacts leading to poor conductivity.
  
• Internal mechanical failure from repeated switching cycles.
  
• Moisture ingress or corrosion inside the switch assembly.
  
• Connector damage or wiring faults reducing reliability.
  
• Age-related deterioration of plastic housings or springs.

Symptoms of failure can include the rear wiper not activating, operating intermittently, or the washer system failing to spray.

Why Replace a Faulty Rear Wiper Switch?

A malfunctioning switch can severely affect rear visibility and driving safety — particularly in wet or winter conditions. Replacing the faulty part restores full wiper and washer control, ensuring optimal rearward vision.

Benefits of replacement include:

• Restored and responsive wiper and washer operation.
• Improved rear visibility in all weather conditions.
• Enhanced driver safety and comfort.
• Manufacturer-level performance, fitment, and reliability.

Each replacement switch in this range is built to high standards ensuring perfect integration and dependable performance for years of safe driving.
