The low-pressure port on the A/C system of a 2002 Dodge Caravan is typically located
on the drier/accumulator. The drier/accumulator is part of the A/C system and is usually found near the firewall on the passenger side of the engine compartment. It's a cylindrical component, often with several fittings. The low-pressure port will usually be smaller than the high-pressure port.
However, you should consult a repair manual specific to your 2002 Dodge Caravan's year, make, and model. The exact location might vary slightly depending on the specific configuration. Improperly accessing these ports can lead to injury or damage to the A/C system. If you are unsure, it's best to have a qualified mechanic perform any A/C work.
