Description:
The early LCDs suffer from the claim of long life and give up their function after more than a decade in use. So the climate control display is also a typical defective component on the Porsche Boxster. With this repair kit, you can solve the problem cheaply and in the long run.
Tip:
We advise against buying an air conditioning control unit that is "still intact": it is only a matter of time before the display here has also reached its life expectancy and expires. Therefore, it is better to save time, money and aggravation right away and install a display that was manufactured true to the original with the help of modern manufacturing technology and tighter tolerances.
Repair note:
The installation should be done by a professional, but is supported by an illustrated manual in the languages DE/EN/FR/ES/RU/IT.
Only a screwdriver and needle nose pliers are required for the swap. No soldering work is required.
Design:
The LCD corresponds to the Porsche original design and is not a "similar" third-party solution. Partially Audi displays are installed, whose installation requires adjustment work in the housing and do not have the original design.
Our LCD also takes into account the differences between first and second generation.

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.
