Where is the orifice tube on 2001 suburban?

On a 2001 Chevrolet Suburban, the orifice tube is located in the refrigerant line that runs between the condenser and the evaporator. Specifically, it can usually be found on the high-pressure side, typically near the evaporator core or within the accumulator. To access it, you may need to remove some components, as it is often situated in a tight space. Always refer to a repair manual for detailed instructions and diagrams.
