The lack of precious cold air could be caused by a Freon leak caused by a failed o-ring, seal, hose or component, a clogged expansion tube or refrigerant charging hose, failed compressor or compressor clutch failed blower motor or blower motor resistor, damaged or failed condenser or evaporator, and or vacuum leaks, failed switch, fuse, relay, control module, blend door or solenoid.
