What kind of air conditioning does a 97 Jeep Grand Cherekee use?

A 1997 Jeep Grand Cherokee uses a conventional refrigerant-based air conditioning system. It's not a specific type beyond that; it's a standard automotive AC system using a compressor, condenser, evaporator, and expansion valve (or orifice tube) to cool the air. The specific refrigerant used in a 1997 model would likely be R-134a, as R-12 was phased out around that time. However, it's always best to check the vehicle's sticker or documentation for the exact refrigerant type.
