The low side service port the for air conditioner is located on the large tube /hose coming from the fire wall to the rear of the compressor. Here is a some guides that will help you get the job done and to see how the system works and what goes wrong with it. Here are videos and guides to show you how to recharge your air condition system and find the charge port.
