2003 Chevrolet ACH: Location of Expansion Tube?

On 2003 Chevy Model.
The expansion block/orifice tube is located inside the evaporator tube. You will need a special tool: J 26549-E Orifice Tube Remover - to remove the orifice tube from the evaporator tube.
You can usually rent this tool from any local "big chain" parts store.
