Four Seasons A/C Evaporator Core P/N:54150
Four Seasons 54979 A/C evaporator core for the 2001-2005 Lexus IS300 and other vehicles absorbs heat from cabin air as refrigerant passes through it. The core design meets or exceeds OE performance and efficiency.
Weak cooling, a musty smell from the vents or refrigerant loss can mean the evaporator core is leaking or clogged. These signs alone do not prove the core is at fault, since a low refrigerant charge can cause weak cooling too. This listing is one evaporator core, and each car takes one.
This evaporator core is a direct-fit replacement for the 2001-2005 Lexus IS300 and the 1999-2003 Lexus RX300.
