ROLLS ROYCE PHANTOM MK7 VII 7 climate control panel

For the Rolls-Royce Phantom VII (RR1), the climate control system—often referred to as the IHKA (Integrated Heating and Air Conditioning) unit—is a classic example of “analog elegance” masking deep digital complexity.

By 2026, original parts for the MK7 (2003–2017) are largely sourced as high-quality used modules or “New Old Stock” (NOS).

1. Core Component Part Numbers

The Phantom VII uses separate control interfaces for the front and rear passengers. The front panel is distinctive for its lack of a digital temperature screen, instead using rotating “violin key” switches and traditional dials.

2. Technical Operation: The “Independent” System

The Phantom VII climate system is unique because it emphasizes independent airflow volume over numerical temperature settings.

• Dual Airflow: Unlike standard cars, the Phantom allows you to independently adjust the temperature of the “upper” vents (face) and “lower” vents (feet) simultaneously.

• Humidification: The system is designed not just to cool, but to maintain a specific humidity level to prevent the premium leather and wood veneers from drying out or cracking over time.

• Silent Fans: The blower motor is mounted on specialized rubber “silent blocks.” If you hear a high-pitched squeak or “chirp,” the motor’s bearings are failing (Common Issue in 2026 for early 2003-2009 models).
