BMW Heating & Air Conditioning for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

Is your BMW blowing hot air when you want AC? Not getting enough hot air when it's cold out? Well we have the heater cores, heater valves, blower motors and related parts for your BMW. Tip: Is your air conditioning / heater fan going crazy? Does it only run at one speed or not work at all? Then a likely culprit is this blower resistor, often called the "final stage unit" in the BMW world. The function of this part is to regulate the voltage of the blower motor on BMWs which use the digital climate control. This blower resistor is a notorious weakness on the cars that use it. When it fails, your blower fan speed can fluctuate as if it has a mind of its own, or get stuck at one position. BMW has updated this item several times and we only carry the most current version.

Next time you perform maintenance on your vehicle, don't forget to change your cabin air filter. Cain filters are an important part of the climate control system that filters out contaminants in the air that you breathe. If you have noticed that your heat or A/C is not blowing as strong as normal, this could be due to a clogged filter. Swap out your dirty, old filter to ensure your air is clean and easy-flowing! Cabin filters should be changed out every 30,000 miles to maintain optimal comfort. If you have noticed reduced airflow through your HVAC system before this point, the filter is most likely clogged and should be replaced early to prevent air pollutants from circulating through the vehicle's cabin.
