Automotive Solutions from Spaanstra Bros. Automotive Service: Air Blend Box



Let’s break it down. First there is the blower fan that circulates the air through the heating/air conditioning system. The fan can blow at different speeds, depending on how much hot or cold air is necessary to be comfortable. The blend box can either convey fresh air from outside, or recirculate air from inside the cabin. Grand Rapids auto owners often choose to recirculate air when first starting the vehicle until it starts to either cool down or warm up.

The next thing the blend box does is bring airflow over the heater core to warm the air, or over the air conditioner evaporator core to chill it – or a blend of hot and cold to get it just right. From there the blend box can direct the air out into the passenger compartment through the floor vents, the panel vents, the defroster, or a combination. All of this allows Grand Rapids motorists to customize the climate just the way the like it.

Some vehicles have different climate control zones, like one for the driver and one for the passenger – or even more zones for the back seat. Additional blend boxes are used for this. Climate controls could be manually adjusted or computer controlled depending on your vehicle.

The blower motor and all of the little actuator motors that open and close the various blend doors can fail and need to be replaced. Most new vehicles come with a cabin air filter. This filter cleans the air before it gets into the blend box. If you neglect changing the cabin air filter, it can get clogged, smelly, and even allow mildew and other microorganisms to build up in the blend box.

Spaanstra Bros. Automotive Service in Grand Rapids can complete a heating/air conditioning system cleaning service that will clean and disinfect the system, restoring a fresh clean scent. If you are not getting enough hot or cold air, Spaanstra Bros. Automotive Service can survey your system, diagnose the cause and set things right. And don’t forget to replace the cabin air filter on schedule. In addition, if you live and drive in dusty Grand Rapids conditions or where there is a lot of pollen or other pollutants, you may need to replace your cabin air filter more frequently.
