To be absolutely certain:
* Check the part numbers: Find the part number on your 1995 Lumina's compressor and compare it to the part number of the 1996 compressor you're considering. If the numbers match, they are interchangeable.
* Consult a parts store: Take the compressor part number from your 1995 Lumina to an auto parts store (AutoZone, Advance Auto, etc.) and ask if a 1996 compressor is compatible. They have access to databases that can confirm compatibility.
Don't solely rely on the model year. Part numbers are the definitive way to ensure compatibility.
