Inside the A/C system, the evaporator core pulls heat from cabin air, and the Four Seasons 54497 front a/c evaporator core for the 1976-1977 GMC Jimmy and other vehicles is a plate and fin design.
- Engineered and tested for years of trouble-free operation, backed by over 50 years of mobile A/C experience
- Core design meets or exceeds OE performance and efficiency
- Optimized refrigerant flow
- Application specific design
A failing evaporator core can show up as weak cooling at the vents or a musty smell from the dash. Before replacing it, look over the A/C lines and fittings with the engine off for oily residue, because a leak elsewhere in the system can leave the cabin warm too. A shop can run the pressure tests.
It fits the 1976-1977 GMC C1500 and the 1976-1977 GMC C2500, along with a wide range of other Chevrolet and GMC models from those years. If your vehicle isn't one of these, open the "Vehicles it fits" section and check your exact model and engine there.
