Where is the low pressure air conditioner charge fitting located for a 2002 jeep liberty?

The low pressure air conditioner charge fitting on a 2002 Jeep Liberty is typically located on the larger diameter line that runs between the evaporator and the compressor. It is usually situated near the front of the engine compartment, close to the driver's side. Look for a service port with a plastic cap, which may be labeled with an "L" for low pressure. Always ensure the engine is off and the system is not under pressure before attempting to access the fitting.
