On a 1994 Z28 LT1 motor, the low-pressure port for the air conditioning system is typically located on the accumulator, which is situated near the passenger side of the engine bay. It is usually a smaller port with a blue or black plastic cap. To locate it, follow the refrigerant lines from the compressor; the low-pressure port will be closer to the evaporator. Always ensure the system is not under pressure before attempting to service it.
