BMW M3 Heater and Air Conditioning Parts

Without a high-quality OEM heater and air conditioning system, your BMW M3 cabin wouldn't warm or cool well. Factory HVAC systems in any BMW work straightforwardly. Like a radiator, the heater in your BMW M3 passes hot engine coolant through a heater core as a fan blows air from outside over the core's fins. The resulting warm air fills your interior, making it more comfortable on chillier days. Your BMW M3 air conditioning works in stages, starting with a compressor that turns pressurized refrigerant into a hot gas. A condenser then cools the gas, turning it back into a liquid. That fluid heads through an expansion valve, turning into a low-pressure gas, where an evaporator rapidly chills it by fanning. This generates the cold air that heads down your ducts and through your vents, cooling off your cabin on hot days. Over time, even an original BMW M3 heater and air conditioning system can run down. Weakening seals, cracked or broken hoses, and compressor failure can be the causes. Signs your car heating isn't working, however, range from clogs and corroded parts to a sweet coolant smell accompanying a steamy interior. The latter indicates a likely heater core leak. There's usually one sign your car air conditioning isn't working properly: the system isn't cooling. Leaking refrigerant, low refrigerant levels, or both can be the causes.
