Where the low pressure side connector on 2002 chev venture vans?

On a 2002 Chevrolet Venture, the low-pressure AC fitting is typically located on the dryer/accumulator. The dryer/accumulator is part of the AC system and is usually found near the firewall on the passenger side, often somewhat tucked away. It's a cylindrical canister, and the low-pressure port will be smaller than the high-pressure port.

Important Note: It's crucial to be absolutely certain you're working on the low-pressure side before attempting any work on the AC system. High-pressure refrigerant can cause serious injury. If you are unsure about its location, consult a repair manual specific to your 2002 Chevrolet Venture or a qualified mechanic. Improper handling of refrigerant can also damage the environment.
