Why replace this relay?

Loss of intermittent function — the most common symptom: intermittent (delay) wipe stops working while continuous speeds still operate. Many owners find the delay knob produces one sweep only or nothing.

Wipers stuck on / won’t stop — relay contacts or internal timer failure can leave wipers running or behaving unpredictably. Forum reports show both “wipers won’t turn off” and “wipers run continuously” symptoms tied to the relay or associated wiring.

Intermittent clicking / no response — relay may stop clicking or click but not switch the motor circuit due to worn contacts or internal failure. Swapping relay is a common test. 

Common issues & fault causes

Worn internal contacts / timer fault — relay internals degrade with age and use, causing loss of the pulse/interval function.

Corroded connector or fuse/relay carrier contacts — poor connection at the fuse/relay panel can mimic relay failure; cleaning contact points often fixes intermittent faults.

Related component faults — sometimes the wiper stalk/switch or the wiper motor itself causes similar symptoms; common troubleshooting is to test/swap the relay first, then check the stalk and motor.

Shorts / blown fuses — seized motor or wiring short can blow fuses or overload circuits; a failing relay can also cause abnormal current behaviour.

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.
