On a 1999 GMC Jimmy, the low-pressure air conditioning fitting is typically located on the larger diameter aluminum line between the evaporator and the compressor. It's usually near the front of the engine compartment, often on the passenger side. You can identify it by its larger size compared to the high-pressure fitting and the blue or black plastic cap.
