Electric Window Relay 

Restore reliable operation of your Porsche's electric windows with this OE Match Electric Window Relay. This relay controls the electrical power supplied to the power window system, ensuring smooth, dependable operation every time you press the window switch.

Fits:

  • Porsche 944S2 3.0L 16V 1989-91
  • Porsche 944 Turbo 2.5L 8V 1989-91
  • Porsche 968 3.0L 1992-94
  • Porsche 968 Sport 3.0L 1994-95
  • Porsche 968 CS 3.0L 1993-95
  • Porsche 968 Turbo S 3.0L 1993-94
  • Porsche 928GT 5.0L 1989-91
  • Porsche 928GTS 5.4L 1992-95

This OE Match relay installs directly into the factory relay board using the original relay location, making it an ideal replacement for worn, ageing or failed original relays.

Whether you're repairing intermittent window faults or carrying out preventative maintenance, using a OE Match relay ensures the correct electrical performance, durability and compatibility expected from an original factory component.

What Does the Electric Window Relay Do?

The electric window relay is an essential part of the vehicle's power window electrical circuit.

Its functions include:

  • Controlling power delivery to the electric window motors.
  • Providing switched electrical current to the window system.
  • Protecting window switches from carrying high electrical loads.
  • Ensuring smooth and reliable window operation.
  • Supporting safe and consistent operation of both driver and passenger windows.

Without a correctly functioning relay, the power window system may not receive the electrical supply required for normal operation.

Why Do Electric Window Relays Fail?

Electrical relays operate every time the windows are used and are subjected to thousands of switching cycles throughout their service life.

Common causes of failure include:

  • Internal contact wear.
  • Heat generated by repeated electrical switching.
  • Oxidation of electrical contacts.
  • Age-related deterioration of internal components.
  • Moisture entering the relay board.
  • High electrical loads caused by ageing window motors or regulators.

As the relay ages, internal resistance increases, leading to unreliable or intermittent electrical operation.

When Should the Relay Be Replaced?

Replacement is recommended when:

  • Electric windows stop working intermittently.
  • Both windows fail to operate despite good switches and motors.
  • The relay clicks but the windows do not move.
  • Window operation becomes unreliable.
  • Diagnosing electrical faults within the power window system.
  • Restoring an original Porsche electrical system.
  • Carrying out preventative maintenance on higher-mileage vehicles.

Replacing a faulty relay is often one of the quickest and most cost-effective ways to restore dependable electric window operation.

OE Match Features

  • OE Match quality replacement.
  • Manufactured to closely replicate original factory specifications.
  • Plug-and-play installation.
  • Correct switching characteristics for factory electrical systems.
  • High-quality internal contacts for dependable operation.
  • Durable construction for long service life.
  • Ideal for restoration, repair and preventative maintenance.       

Relay Board Location

For easy identification during installation:

  • Porsche 944 / 968: Relay board position G7
  • Porsche 928: Relay board position VI

Always verify the relay location using the appropriate workshop manual for your specific model year.

About Relays / Fuses

Relays and Fuses – Electrical Protection and Performance for Porsche Vehicles

Relays and fuses are critical components in your Porsche’s electrical system, ensuring that power is delivered safely and reliably to every circuit. From the ignition and lighting systems to the fuel pump and cooling fans, these components protect wiring and electrical modules from overload, short circuits, and potential failure.

At Design911, we stock a comprehensive selection of genuine and high quality relays and fuses for all Porsche models - including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each part is built to the highest standards to ensure dependable performance and precise compatibility with your vehicle’s electrical system.

What Do Relays and Fuses Do?

Fuses act as the first line of defence in your vehicle’s electrical circuits. They break the circuit when current exceeds safe levels, preventing damage to components or wiring.

Relays
act as electronic switches that control high-current devices using low-current signals. They allow systems like headlights, fuel pumps, fans, and wipers to operate efficiently without overloading the control switches.

Together, they form a vital network that maintains safety, functionality, and reliability across your Porsche’s electrical system.

Why Do Relays and Fuses Fail?

Over time, electrical components are subject to wear, heat, and environmental factors that can lead to failure. Common causes include:

  • Overheating or overcurrent loads blowing the fuse.
  • Aging or corroded relay contacts leading to intermittent operation.
  • Moisture ingress or corrosion within the fuse box or relay socket.
  • Vibration or mechanical stress loosening connections.
  • Electrical short circuits caused by wiring faults or damaged insulation.

Symptoms of faulty relays or fuses can include malfunctioning lights, non-start conditions, intermittent accessory operation, or completely dead electrical systems.

Why Replace Faulty Relays and Fuses?

Replacing worn or damaged relays and fuses is essential to maintain your Porsche’s electrical integrity and prevent more serious system failures. Using quality replacements ensures proper current flow, system protection, and long-term reliability.

Benefits of replacement include:
Restored function of electrical systems and accessories.
Protection from wiring damage or electrical fires.
Enhanced safety and dependability.
High-level quality and fitment for lasting performance.

Every relay and fuse in this range is precision-tested and manufactured to match factory specifications, ensuring seamless compatibility and peace of mind on the road.
