Four Seasons A/C Evaporator Core P/N:54150
Four Seasons 54599 rear A/C evaporator core for the 1995-1996 Chevrolet Tahoe and other vehicles cools cabin air as refrigerant flows through it. The core design meets or exceeds OE performance and efficiency.
Weak cooling from the rear A/C, oily residue at the fittings or repeated refrigerant loss can mean the evaporator core is worn, though a faulty expansion valve or a weak blower motor can be behind the same signs, so find the cause before replacing the core.
It is a direct-fit replacement for a wide range of Chevrolet and GMC models, including the 1994-1996 GMC Yukon and the 1994 Chevrolet Suburban. The rear A/C system takes one. If your truck is not one of those, look it up in the "Vehicles it fits" section.
