This small internal fan draws cabin air across the temperature sensor, allowing the climate control system to monitor interior temperature and adjust heating accordingly.

Featuring a modern brushless motor with hydraulic bearings, it offers quiet operation and improved durability compared with the ageing original fan.

What Does It Do?

The fan continuously draws cabin air across the internal temperature sensor inside the HVAC control unit.

This enables the system to measure cabin temperature correctly and regulate heating and ventilation.

Why Is It Important?

Without adequate airflow across the sensor, the climate control system may receive inaccurate temperature readings.

This can result in poor heating performance, incorrect temperature regulation or the cabin becoming progressively colder while driving.

Why Do HVAC Control Fans Fail?

Common causes include:

• Worn motor bearings
• Age-related motor failure
• Dust and dirt accumulation
• Electrical wear
• General deterioration after prolonged use

A failing fan often produces a noticeable buzzing or whirring noise behind the dashboard.

When Should It Be Replaced?

Replacement is recommended if the fan becomes noisy, stops operating or causes inconsistent cabin temperature regulation.

It should also be checked when investigating poor heating performance or climate control faults.

Why Choose OE Match?

This upgraded OE Match fan provides a modern replacement for the original Porsche CCU fan.

Its brushless motor and hydraulic bearings offer smoother, quieter operation and improved long-term reliability.

HVAC Climate Control Fans

The Porsche 964 and 993 climate control systems rely on a small internal fan to draw cabin air across the temperature sensor, ensuring accurate heating and ventilation control.

Over time, the original fan motor can become noisy or stop working, leading to poor temperature regulation.

The OE Match upgraded HVAC fan provides a reliable replacement for restoring correct operation of the original climate control unit without replacing the complete assembly.
