MINI R56 vehicles can come equipped with one of two climate control systems: IHKS manually controlled climate control, or IHKA, automatic climate control. Each has multiple sensors, controls, air temperature units and ducts, with IHKA having additional components to handle auto temp control. The blower motor that controls air flow 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.

If your blower motor fails, replace the blower and resistor together. You don't want to have to go back in if one fails later. Over time, a blower motor may become noisy as the motor electrical contacts wear. The blower fan cages also fracture, creating a vibration when the blower is ON. If it fails or becomes noisy, you can use this procedure for the repairs.

Replacing the blower motor is no easy task. You will have to work high up behind the instrument panel in an uncomfortable position. 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).
Figure 1

The blower final stage is located above the accelerator pedal in the heater housing (green arrow). With the lower kick panel removed, remove the two T20 Torx screws from the side panel (red arrows).

Then, remove the side panel from the center tunnel (red arrow).
Figure 2

Then, remove the side panel from the center tunnel (red arrow). Slide it toward the rear of the vehicle to remove it.

The green arrow points to the blower motor.
Figure 3

The green arrow points to the blower motor. Start by squeezing the electrical connector release tabs (red arrows) and pulling the connector straight out to remove it.

Now it is time to remove the three blower motor screws.
Figure 4

Now it is time to remove the three blower motor screws. I like to use a long extension with a 1/4-inch drive T20 Torx bit (inset) on a universal adapter. Start with the rear most screw (red arrow), located just above the blower electrical connector. You will have to lie on your back, looking up past the accelerator pedal. Loosen the screw using the ratchet. Then remove the bit from the ratchet and remove the screw by hand.

Then, remove the two front screws.
Figure 5

Then, remove the two front screws. Use the long extension again, top one first, then the bottom one (red arrows).

Pull the blower motor straight out of the heater housing (green arrow).
Figure 6

Pull the blower motor straight out of the heater housing (green arrow). Move the wiring harnesses aside (red arrows) as you pull it out.

To remove the motor, angle the covered end down.
Figure 7

To remove the motor, angle the covered end down. Then remove the small hose from the heater housing (green arrow). Slide the motor down (red arrow). Wiggle it past the steering column shaft. Note the orientation the motor comes out as you lower it.

Press the accelerator pedal down (red arrow) and slide the motor past it.
Figure 8

Press the accelerator pedal down (red arrow) and slide the motor past it. Remove the blower motor from the vehicle. Install the motor the in reverse of removal. Slide it up, cage first. Be sure the mounting flange for the rear most screw is orientated toward the rear. It will not rotate once it is up. Slide up and past the wiring, then into the heater housing. Install the screws and finally the electrical connector and trim panels.
