An Air Conditioning system has a Compressor, Condenser, Evaporator, and Accumulator. If your car A/C system does not work effectively, you will not be able to enjoy the usually cooling effect. The Expansion valve is one of the major components in your BMW A/C system. It regulates the flow of gas inside the A/C system and it controls the flow of refrigerant according to how cool you want it to get inside your car.
If you crank up the A/C system, the expansion valve expands and releases more refrigerant through the system. If you turn the A/C System down, the expansion valve shrinks which decreases the amount of refrigerant. If you find any difference in the performance of your BMW A/C expansion valve, you need to replace it as soon as possible. You are at the right place to get top of the line BMW car parts.
