Most Porsche 964 and 993 owners now see the end of their CCU fan service life, causing a noticeable whirr or buzzing sound behind the dashboard. The fan will eventually stop, causing problems with temperature regulation. This small fan is imperative for correct control of the cabin temperature, and a non-op fan will make your cabin temperature slowly decrease during driving. This fan costs USD120 when changed in conjunction with our CCU repair services.
You'll need a set of CCU removal tools to change the fan.
Replaces Porsche part# 96465914800 or 96465914802

Please be aware that the Climate Control Unit will indicate an OBD Interior Sensor fan fault code due to the much lower current consumption of this fan. This fault code can be ignored and does not affect the operation of the unit nor the fan.

Porsche Climate Control Systems & Components | Precision Cabin Comfort & Temperature Management
The climate control system in your Porsche maintains perfect cabin temperature and air quality by automatically regulating heating, cooling, and ventilation. Using a combination of sensors, actuators, and control units, it adjusts airflow and temperature to create a consistent and comfortable driving environment — regardless of outside conditions.
At Design911, we offer premium climate control panels, modules, sensors, and actuators designed to meet or exceed original performance standards. Built using advanced materials and precision electronic calibration, our components restore seamless climate management, accurate temperature regulation, and reliable HVAC functionality for all Porsche models.
Whether you’re repairing a faulty control panel, replacing a temperature sensor, or restoring full automatic climate functionality, our Porsche climate control parts deliver the reliability, precision, and comfort you expect.
What Does the Climate Control System Do?
The climate control system automatically manages cabin heating, cooling, and ventilation by regulating air temperature, fan speed, and airflow direction.
Core Functions:
- Monitors and adjusts cabin and exterior temperature balance.
- Controls airflow through the heater core and A/C evaporator.
- Regulates humidity and defogging for optimal visibility.
- Automatically maintains selected temperature settings.
- Provides driver and passenger comfort through precise control modules.
A well-functioning system ensures comfort and safety, keeping cabin conditions ideal year-round.
Why Do Climate Control Systems Fail or Malfunction?
Because the system integrates electronic, mechanical, and air distribution components, it is vulnerable to wear, contamination, or electrical failure over time.
Common Causes of Failure Include:
- Faulty control panels or digital interfaces.
- Damaged temperature or sunlight sensors.
- Malfunctioning air distribution flaps or servo motors.
- Electrical faults in actuators or wiring harnesses.
- Blocked ventilation ducts or faulty blower motors.
Symptoms of a failing system include inconsistent cabin temperature, non-responsive controls, fogged windows, or unbalanced airflow between zones.
Why Replace Your Porsche Climate Control Components?
Replacing or upgrading malfunctioning climate control components restores reliable temperature management and consistent comfort. High-quality parts ensure proper system communication, energy efficiency, and long-term reliability.
Key Benefits:
- Restores smooth, accurate temperature regulation.
- Improves air distribution and cabin comfort.
- Ensures A/C and heating systems function efficiently.
- Reduces condensation and prevents window fogging.
