Four Seasons A/C Evaporator Core P/N:64019
Four Seasons 54845 A/C evaporator core for the 2006-2010 Hummer H3 and other vehicles removes heat from the cabin air as refrigerant evaporates inside it. The core design meets or exceeds OE performance and efficiency.
Weak cooling, a musty smell from the vents or refrigerant leaking at the core can mean the core has failed. Those signs alone do not prove the core is the problem, since a low refrigerant charge can also leave the air warm.
Vehicles it fits include the 2006-2010 Hummer H3, the 2009-2010 Hummer H3T and the 2007-2010 Saturn Sky, and each takes one core. If your car is not named here, open the "Vehicles it fits" section and check your exact model and engine.
