The blower-regulator wiring harness in your vehicle is a network of wires and connectors that controls the temperature in your car. In some 2008-2012 BMW 1-series models, this wiring can get too hot and potentially overheat.
Risk if Unfixed
If the wiring overheats, it could melt the electrical connectors and increase the risk of a fire, even when you're not driving the car.
Free Fix
Your BMW dealer will inspect the blower-regulator wiring harness and replace it with a new one, completely free of charge. You'll receive a notification and should schedule the repair as soon as possible.
