The Rennline HVAC control panel is CNC milled from a billet aluminum block and anodized for a classic and elegant dash upgrade. Whether you're trying to clean up the dash on your early 911, or backdating the dash on your G-body car, these HVAC controls are sure to do the job. Featuring simplified markings and updated micro LED indicators, the unit pairs very well with our I12 Billet HVAC Knobs (not included but available separately). OEM plastic units are prone to scratching and fading, while these units are proven to stand the test of time. Installs easily to factory control mechanism.
Note: If installing in a 74-89 car, the dash must be backdated as these controls are smaller than the later controls.

Porsche Heating & Air Conditioning Housings | Precision Airflow & Climate System Integrity
The heating and air conditioning housing is the core structure that contains and directs airflow through your Porsche’s HVAC system. It houses essential components such as the blower motor, evaporator, heater core, and flaps — ensuring proper distribution of warm and cool air throughout the cabin. A well-sealed, correctly aligned housing maintains efficiency, airflow balance, and consistent cabin comfort.
At Design911, we offer high-quality heating and air conditioning housings designed to meet or exceed original performance standards. Built from durable, heat-resistant plastics or composite materials, these housings ensure perfect fitment, secure sealing, and long-term resistance to vibration and temperature changes.
Whether you’re restoring a classic air-cooled Porsche or maintaining a modern climate control system, our HVAC housings deliver dependable performance, improved air circulation, and precise climate regulation.
What Do Heating & Air Conditioning Housings Do?
The housing acts as the backbone of the HVAC system — securing and protecting the main components while directing air to the appropriate zones inside the cabin.
Core Functions:
- Encases the heater core, evaporator, and air distribution components.
- Directs airflow between heating, cooling, and defrosting circuits.
- Maintains system pressure and ensures efficient air movement.
- Prevents temperature loss and air leaks within the ventilation system.
- Supports the integration of climate control sensors and actuators.
Without a properly sealed housing, the HVAC system cannot deliver balanced airflow or maintain temperature consistency, reducing comfort and efficiency.
Why Do Heating & A/C Housings Fail or Degrade?
Although built for durability, housings are exposed to constant vibration, temperature fluctuations, and moisture — all of which can lead to wear or structural failure over time.
Common Causes of Failure Include:
- Cracked or warped plastic due to heat cycles.
- Damaged mounting points or seals causing air leaks.
- Corrosion
around metal fasteners or brackets.
- Blockages or debris buildup restricting airflow.
- Misalignment from improper servicing or accident damage.
- Blockages or debris buildup restricting airflow.
- Misalignment from improper servicing or accident damage.
A damaged housing can cause weak airflow, inconsistent heating or cooling, and unwanted cabin noise.
Why Replace Your Porsche Heating / A/C Housing?
Replacing a cracked or leaking housing restores correct airflow, seals, and structural integrity within your HVAC system — ensuring reliable temperature control and quiet operation.
Key Benefits:
- Restores efficient airflow and proper temperature regulation.
- Prevents air leaks and loss of heating or cooling performance.
- Ensures secure mounting for HVAC components.
- Reduces cabin noise and vibration.
