* Faulty compressor: The compressor is the heart of the air conditioning system and is responsible for compressing the refrigerant and circulating it through the system. If the compressor is faulty, it will not be able to compress the refrigerant and the system will not be able to cool the air.
* Faulty condenser: The condenser is responsible for dissipating heat from the refrigerant. If the condenser is faulty, it will not be able to dissipate heat and the system will not be able to cool the air.
* Faulty evaporator: The evaporator is responsible for absorbing heat from the air. If the evaporator is faulty, it will not be able to absorb heat and the system will not be able to cool the air.
* Faulty expansion valve or orifice tube: The expansion valve or orifice tube is responsible for controlling the flow of refrigerant into the evaporator. If the expansion valve or orifice tube is faulty, it will not be able to control the flow of refrigerant and the system will not be able to cool the air.
* Electrical issues: Electrical issues such as a faulty blower motor, relay, or switch can also cause your Jeep to only blow cold air.
