Today we looked at a 2019 BMW X1 with a concern about the climate control system. Our technician scanned the vehicle and found multiple fault codes pointing to the passenger side blend door. After researching the concern and finding a BMW technical service bulletin related to blend door housing damage, we removed the actuator for inspection and discovered the heater box itself is damaged β a critical gear that engages the blend door is broken and missing. The heater box will need to be replaced to properly restore the climate control system on this vehicle. If you're in South Windsor or the surrounding area and your vehicle isn't controlling temperature the way it should, this is exactly the kind of hidden damage that a thorough diagnostic process uncovers β and why we don't just swap parts and hope for the best.
