Mercedes HVAC Heater Core - Nissens 0028355201

Product Information

The HVAC heater core is a small radiator-like component located within the vehicle's HVAC (Heating, Ventilation, and Air Conditioning) system. It transfers heat from the engine coolant into the cabin, warming the air that passes through the HVAC system and providing heat to the vehicle’s interior. As hot coolant flows through the heater core, the blower motor pushes air over it, and the heated air is then directed into the cabin.

• Weak or No Heat in the Cabin: If the heater core is partially or fully clogged, the warm air may not reach the cabin effectively, resulting in weak or no heat even when the heater is turned on high
• Sweet or Musty Smell in the Cabin: The heater core contains engine coolant, which has a distinctive sweet smell. If there’s a leak, you may notice this odor inside the car. Over time, this smell can become musty as the leaking coolant sits in the ventilation system
• Fogged-Up Windows: A leaking heater core can allow coolant to enter the HVAC system, which then evaporates onto the windshield, causing a foggy or hazy layer on the inside of the windows. This fog is often sticky and hard to wipe away.
