The interior of your Mazda is not only comfortable because the seats are nice and the arm rests fit; it is comfortable because the climate inside the cabin is a nice temperature. This is because the heating and cooling system on your Mazda is operating properly. Many parts make up the HVAC system on your vehicle. There are hoses, valves, compressors, condensers, coils, cores, vents, filters, pumps and belts that all work together to deliver a comfortable temperature during hot and cold months.
The air conditioning system is driven by a compressor that is connected to the engine by way of a belt. The compressor takes refrigerant and moves it through a series of components that condense it, heat it and then cool it in order to deliver cold air into the cabin. The heater has a core that the water from the engine flows through. Regardless of whether it is hot air or cold air, all air travels through a series of ducts and is pushed along by fans and blowers. This creates a comfortable climate for you that makes it possible to drive during any weather.
These parts can go bad, and they are under a lot of pressure, so they may need to be replaced. When you replace any of the parts in your heating or cooling system for your Mazda B2500 or B3000, use an OEM Mazda part for an exact fit replacement part.
