BMW 740il Heater and Air Conditioning Parts

Heating and cooling the cabin of your BMW 740il sedan would be impossible without a dependable factory HVAC system. The heater and air conditioning systems in any car works straightforwardly. Your BMW 740il heater, for one, operates like a radiator. It takes hot engine coolant and sends it through a small heater core. The fan upfront blows cooler outside air over the core's fins. This is the way your heating system warms your interior as you drive. The air conditioning in your BMW 740il, on the other hand, works in four parts. Its compressor first turns refrigerant under pressure into a hot gas. Then, its condenser cools the gas back to a liquid. The resulting fluid then travels to the AC's expansion valve. As it passes through it, liquid turns to low-pressure gas. Your evaporator then rapidly chills the gas using a fan. This creates the cool air that travels through your ducts, out your vents, and into your cabin. Over time, even a high-quality BMW 740il heater and air conditioning system straight from the OEM can run down. Its seals weaken, its hoses crack and break, and even the compressor in your AC can fail. When your car heating is not working, signs like clogs, corrosion, a sweet coolant smell, and a cabin full of steam can appear. This means a probable heater core leak. When your car air conditioning stops working right, it often has one sign: the system doesn't cool. This could mean leaking refrigerant, low refrigerant levels, or both.
