BMW 3-Series AC Parts & Heating Parts

Introduced in the 1930s, the air conditioning system has become more and more important with the increasing use of automobiles in modern society and with the time people spend in their cars, which is constantly growing today. Queuing in traffic under the summer sun or taking a long journey during a rainy and humid day would be inconceivable without the A/C system. The comfort of the cabin, in fact, depends largely on this system, which cooperates with the heating and ventilation system to provide comfortable levels of warmth, coldness, and humidity. The reliability of the A/C system in the BMW 3-Series is generally high, but over time it can give you troubles like blowing insufficiently cold air or not working at all. On the 3-Series E46, the system can develop a leak during winter months, when not used for a long time.

The compressor, condenser, and evaporator are the main parts in the A/C system, operated via the A/C control module, the 'brain' that monitors the data concerning the temperature and humidity, adapting the system response in order to maintain the cabin comfy and the ride enjoyable. Leakages, worn-out sensors, failures of the blower or fan are among the most common causes of problems in the A/C system.
