Ford Air Conditioning Expansion Valve — HL3Z-19849-D
Is your Ford blowing hot air or cooling erratically, especially in the summer heat? The air conditioning expansion valve is one of the most common causes of weak or malfunctioning air conditioning systems. This valve regulates the flow of refrigerant to the evaporator; when it becomes clogged, stuck, or malfunctions, your air conditioning system loses its ability to cool properly. This is a well-known wear point in the Ford F-Series range, and the summer heat puts extra strain on an already weakened valve, often causing it to fail when you need cool air the most.
