Nissens automotive heater and cabin blowers

Published:  27 October, 2022

Although often overlooked when servicing or repairing the heating, ventilation and air conditioning (HVAC) system, heaters and cabin blowers serve a crucial role, particularly for the comfort of the occupants. So, particularly before the winter season, it is advisable to include these two components during an annual check and, if either need replacement, use only premium quality aftermarket products.

Nissens Automotive (Nissens) is an established aftermarket replacement parts supplier with decades of thermal management experience, across both the vehicle’s engine cooling (EC) and air conditioning (AC) systems. Its comprehensive product range, all of which is manufactured to Genuine Nissens Quality standards, to provide independent workshops with premium grade replacement parts, which operate to the same performance levels as the original, gives them a premium quality aftermarket solution they can depend on.

Heaters

The heater is an integral part of the EC system, but also contributes significantly to the climate system by ensuring the production of warm air to the cabin. It’s often located behind the dashboard or in the HVAC module.

Important to know

  • Scale that settles on interior surfaces and comes from the use of water instead of a proper coolant may block the heater core limiting the coolant flow. Sediment and grime from poor quality coolants, wrong coolant mixtures or residues of cooling system leak stops will also accumulate in the heater tubes limiting flow and reducing the heater’s operating efficiency.
  • A worn-out or broken thermostat valve may restrict coolant flow and so prevent the heater from operating properly.
  • Due to the damp environment in which it’s positioned, the heater is often exposed to corrosion, which may cause leakages.
  • The lack of sufficient coolant caused by leakages (not just in the heater but from other components) will result in improper heater operation.

Blowers

The interior blower ensures the required amount of ambient air is drawn in through the intake and flows through the heat exchangers, i.e. the heater and evaporator. As it passes through the heat exchangers, the air can be either warmed or cooled and is distributed throughout the cabin by the blower. Typically, it is situated in the HVAC module located between the cabin and the engine compartment.

Important to know

  • A clogged or defective cabin air filter can significantly reduce the blower’s lifespan.
  • The most common reasons for interior blower problems stem from failures in the vehicle’s electrical system, restricted flow in the air intake system and improper handling during its installation.
  • Blowers in vehicles used for commercial activities, such as taxis, coaches and buses etc., are often exposed to greater wear simply as a result of the mileage they cover and working hours they operate.
