Which valve is the low pressure service port on your Chevy k1500 ac?

On a Chevy K1500 AC system, the low-pressure service port is typically located on the accumulator/dryer. It's usually a smaller port, often with a blue cap. However, always double-check your vehicle's specific AC system diagram or a repair manual as there can be slight variations depending on the year and specific AC components used. A visual inspection will confirm its location.
