Four Seasons HVAC Heater Control Valve P/N:74601
Four Seasons 74944 heater control valve for the 2014-2019 Fiat 500 controls the flow of engine coolant to the heater core.
Cabin heat that stays cold or hot whatever the setting, or coolant leaking at the valve, can mean the valve is failing. Before you replace the valve, rule out other causes of poor heat, such as a low coolant level (checked only with the engine cool) or a damaged connector or wiring fault.
This is a direct-fit replacement heater control valve for the 2014-2019 Fiat 500.
