What is the air conditioning type for a 1991 Jeep Cherokee?

The 1991 Jeep Cherokee typically uses a R-12 refrigerant air conditioning system. This type of air conditioning is a conventional belt-driven system, which relies on a compressor, condenser, evaporator, and expansion valve to cool the cabin air. If servicing or retrofitting the system, many owners choose to convert to R-134a refrigerant for compatibility with modern standards.
