BMW / MINI - Heater Flap Repair Kit (Errors 801189, 801126)
Heater mixing flap repair spacers restores HVAC temperature control for BMW and MINI vehicles.
Description
The BMW and MINI heater mixing flap repair kit resolves issues with a stuck temperature flap without dismantling the dashboard. The malfunction originates from wear on the factory stops of the mixing flap control shaft. When these stops wear down, the shaft rotates outside its designed operating range, causing the flap to jam in an end position.
This spacer mounts directly between the shaft and the actuator, taking over the function of the original stops and restoring normal system operation. It addresses common malfunctions associated with error codes 801189 and 801126, ensuring the flap travels only within the correct factory parameters.
