Kia Amanti no heat in winter and no air conditioning in summer, possible heater hose or AC charge issue on Kia Amanti

Some Kia Amanti owners report experiencing heating issues in winter and inadequate air conditioning in summer, which may be attributed to problems with the heater hose or insufficient AC charge. Specifically, a blockage or leak in the heater hose can lead to a lack of heat, as it impedes the flow of hot coolant to the heater core. Additionally, low refrigerant levels can cause the air conditioning system to underperform, resulting in the AC not blowing cold air as expected. These issues can significantly impact the vehicle's climate control systems, making it essential for owners to address these areas for proper diagnosis and resolution.
