Diagram Ref No 18

When driving in heavy traffic, tunnels, or polluted environments, the air quality sensor helps prevent exhaust fumes and unpleasant odours from entering the cabin by allowing the system to switch to recirculated air when needed. This supports a cleaner, more comfortable driving experience and helps maintain consistent climate performance.

Over time, air quality sensors can fail due to age, contamination, or electrical issues, leading to incorrect recirculation behaviour and reduced air quality inside the vehicle. Replacing a faulty PAD907659 sensor restores proper HVAC operation and ensures the climate control system responds correctly to changing outside air conditions.

Designed to OEM specifications, this sensor provides direct-fit installation and reliable performance for long-term use.

What This Product Does:

  • Detects pollutants in the incoming air (traffic fumes, exhaust gases, smog)
  • Helps the HVAC system switch between fresh air and recirculation
  • Supports automatic climate comfort and improved in-cabin air quality
  • Works as part of the vehicle’s A/C and heater control system

Symptoms Of Failure:
  • Detects pollutants in the incoming air (traffic fumes, exhaust gases, smog)
  • Helps the HVAC system switch between fresh air and recirculation
  • Supports automatic climate comfort and improved in-cabin air quality
  • Works as part of the vehicle’s A/C and heater control system

Why Replacement Matters:
  • Restore proper automatic HVAC operation
  • Improve cabin air quality in heavy traffic or polluted conditions
  • Reduce unpleasant smells entering the cabin
  • Maintain OEM comfort and climate performance

About Relays / Sensors / Resistors

Porsche HVAC Relays, Sensors & Resistors | Precision Climate Control & System Reliability

Relays, sensors, and resistors are vital components in your Porsche’s heating and air conditioning system. They ensure the correct operation of fans, blowers, and temperature control systems by managing electrical flow, monitoring environmental conditions, and regulating motor speeds. A properly functioning electrical control system ensures reliable, efficient, and responsive climate control performance.

At Design911, we supply premium relays, sensors, and resistors engineered to meet or exceed original performance specifications. Built with high-quality materials and advanced circuitry, these components provide dependable electrical performance and long service life, ensuring your Porsche’s HVAC system operates as smoothly as intended.

Whether you’re diagnosing inconsistent airflow, fan speed issues, or erratic temperature readings, our range of Porsche HVAC relays, sensors, and resistors delivers precise performance, compatibility, and durability.

What Do HVAC Relays, Sensors & Resistors Do?

These components work together to regulate the electrical and mechanical functions of the climate control system.

Core Functions:

  • Relays: Control power to components like blower motors and compressors.
  • Sensors: Monitor temperature, pressure, and humidity for automatic climate adjustment.
  • Resistors: Regulate fan speeds and motor operation.
  • Maintain efficient, stable heating and cooling performance.
  • Protect sensitive electrical components from overloads.

Without functioning relays, sensors, or resistors, the HVAC system may deliver erratic airflow, inaccurate temperatures, or fail to operate entirely.

Why Do HVAC Relays, Sensors & Resistors Fail or Malfunction?

Electrical components endure constant voltage changes, heat cycles, and vibration — all of which can lead to degradation over time.

Common Causes of Failure Include:

  • Corrosion or oxidation on terminals and connectors.
  • Overheating or short circuits caused by electrical surges.
  • Moisture ingress or condensation.
  • Burnt-out resistors due to high current load.
  • Age-related sensor drift or internal failure.

When these components fail, you may notice intermittent fan operation, incorrect cabin temperature readings, or total loss of heating and cooling functionality.

Why Replace Your Porsche HVAC Relays, Sensors & Resistors?

Replacing worn or faulty electrical components restores climate control accuracy and ensures your HVAC system functions efficiently and safely.

Key Benefits:

  • Restores proper temperature regulation and fan control.
  • Prevents electrical faults and inconsistent airflow.
  • Improves reliability and system efficiency.
  • Ensures accurate sensor readings for stable operation.
  • Compatible with Porsche 911, Boxster, Cayman, Panamera, Macan, Cayenne, and classic models.
  • Ideal for diagnostics, maintenance, and complete system refurbishments.

Replacing these components during HVAC servicing helps prevent secondary issues like burnt connectors, blown fuses, or motor failure.

Highlights

  • Precision-engineered Porsche HVAC relays, sensors, and resistors.
  • Designed for accuracy, reliability, and thermal efficiency.
  • Durable, corrosion-resistant materials for long service life.
  • Direct-fit replacements for all Porsche climate systems.
  • Essential for consistent heating, cooling, and fan control.
  • Suitable for repairs, restorations, and system upgrades.
