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 & Fuses – Reliable Electrical Protection for Porsche Vehicles

Relays and fuses are vital components of your Porsche’s electrical system, responsible for controlling power distribution and safeguarding critical circuits. Relays act as electronic switches that manage high-current loads efficiently, while fuses protect your electrical components by breaking the circuit during power surges or faults.

At Design911, we stock an extensive range of genuine and high-quality relays and fuses suitable for all Porsche models, including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each part is precision-engineered for compatibility, durability, and performance, ensuring your Porsche’s electrical system functions safely and efficiently.

What Do Relays and Fuses Do?

These small but essential components perform critical roles in your vehicle’s electrical and safety systems:

  • Relays: Act as electrical switches that control power to key components like the cooling fan, fuel pump, headlights, and ignition system.
  • Fuses: Protect circuits by preventing overloads or short circuits, ensuring safe operation of electrical systems.
  • Together: They maintain stable power distribution and prevent damage to sensitive electronics.

Proper relay and fuse function is essential to keeping your Porsche’s complex electrical systems running reliably under all driving conditions.

Why Do Relays and Fuses Fail?

Over time, relays and fuses can degrade due to heat, vibration, or electrical stress. Common causes of failure include:

  • Corrosion or oxidation on terminals.
  • Overheating caused by excessive current draw.
  • Electrical arcing within relay contacts.
  • Fuse fatigue from repeated current surges.
  • Moisture or contamination affecting performance.

When a relay or fuse fails, systems such as your fuel pump, headlights, air conditioning, or ignition may stop working altogether — leading to performance issues or complete electrical failure.

Why Replace Faulty Relays and Fuses?

A failed relay or blown fuse can cause major system malfunctions or even damage other components. Replacing them with manufacturer-quality parts ensures consistent voltage flow, electrical safety, and reliable system operation.

Benefits of replacement include:

  • Restored functionality to critical electrical systems.
  • Protection against short circuits and overloads.
  • Reduced risk of electrical damage and fire hazards.
  • Long-lasting, dependable performance.

All our relays and fuses are designed using heat-resistant materials and precision contacts, ensuring optimal conductivity, quick response times, and extended service life.
