Keep the air from your dash vents cold with the Four Seasons A/C Evaporator Core, part number 54940 — the plate-and-fin aluminum core where low-pressure refrigerant absorbs heat from the cabin air your blower pushes across its fins. It drops in as a direct-fit replacement for the 2002 Chevrolet TrailBlazer and TrailBlazer EXT, the 2002 GMC Envoy and Envoy XL, and the 2002 Oldsmobile Bravada (engine: All).

  • Plate & fin aluminum core: aluminum construction in a plate-and-fin design for the refrigerant side of the A/C system.
  • Optimized refrigerant flow: engineered to move refrigerant efficiently through the core.
  • OE-level design: core design meets or exceeds OE performance and efficiency, with an application-specific design for the listed vehicles.
  • Seals included: ships with the sealing washers to complete the job — O-ring A (24402) and O-ring B (24404), each a Slim Line Sealing Washer, one of each.

The inlet and outlet use female block-type fittings. Backed by Four Seasons' decades of mobile A/C experience. If a leaking or clogged evaporator core is the cause of weak or warm A/C, this unit replaces it. Manufacturer part number 54940.
