MINI R56 vehicles can come equipped with one of two climate control systems, the IHKS manually controlled climate control, or the IHKA with automatic climate control. Each has multiple sensors, controls, air temperature units and ducts. IHKA has additional components to handle auto temp control. The blower motor that controls airflow into the passenger cabin, is among the most consequential components in the climate control system. The blower motor resistor (or final stage) varies voltage to the blower motor to achieve the desired speed. The blower motor is a D/C electric motor driven by varying current supplied by the blower motor final stage unit.

A faulty final stage could cause the blower to run on and off at varying speeds, without input from driver or to only run at high speed. If you suspect your blower final stage or blower are faulty, see our tech article on blower motor and final stage testing to confirm your suspicion.

Remember that your car may have been serviced before and had parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve, as they grow older. If something seems different, let us know and share your info to help other users.

The blower motor is located behind the center of the dashboard and is serviced from the interior of the vehicle. The blower motor resistor is mounted to the rear of the blower motor.

Remove the left side lower dashboard trim. See our tech article on lower dashboard trim replacement.

The blower final stage is located above the accelerator pedal in the heater housing (green arrow).
