Wiper Motor

Wiper motors are vital components that keep your Porsche’s windscreen clear, providing safe visibility in rain, snow, or dirt conditions. Mounted beneath the windscreen cowl, the wiper motor powers the wiper linkage, converting electrical energy into the precise mechanical movement that sweeps the blades across the glass.

At Design911, we stock a comprehensive range of genuine and aftermarket wiper motors for classic and modern Porsche models - including the 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Every motor is designed for an exact fit and consistent, long-lasting performance.

What Do Wiper Motors Do?
The wiper motor is an electric drive unit that operates the windscreen wipers at variable speeds. When you activate the wiper switch, the motor’s internal gearing and armature generate rotary motion, transferring it through linkages to move the wiper arms.

A quality wiper motor ensures:

• Smooth, even wiping across the windscreen.
• Reliable performance in all weather conditions.
• Integration with intermittent, low, and high-speed modes.

Why Do Wiper Motors Fail?
Over time, wiper motors can wear or fail due to a combination of mechanical and electrical issues, including:

• Motor brush wear or corrosion: Common in older vehicles exposed to moisture.
  
• Seized linkages or frozen arms: Increased resistance can overload the motor.
  
• Electrical faults: Poor wiring, bad ground connections, or blown fuses.
  
• Internal gear wear: Reduces torque and wiping efficiency.

Symptoms of a failing wiper motor include slow or uneven wiper movement, wipers stopping mid-sweep, or complete non-operation.

Why Replace Faulty Wiper Motors?
A defective wiper motor can severely compromise visibility and driving safety. Replacing it ensures your windscreen remains clear in all weather, maintaining safety, comfort, and MOT compliance.

By choosing a genuine Porsche wiper motor, you retain OEM build quality and longevity. For cost-effective repairs, aftermarket alternatives from trusted brands offer excellent performance and compatibility without compromise.

Design911 supplies both genuine Porsche and premium aftermarket wiper motors — all rigorously tested for reliability, precise fitment, and long service life.
