Most GM's put the orfice tube in the output side of the condenser, near the bottom. Locate the fitting that runs from the condenser to the firewall, open that fitting and the orfice tube should be inside.
Many GM vehicles put the AC orifice tube right after the condenser coil. It would typically be near the bottom, almost connected to the condenser. My '99 Suburban AC orifice is located in the line that runs across the passenger side inner-fender. There is a union very close to the innermost edge of the battery tray. Break that union (after relieving pressure) and you will find it there.
Most GM trucks/SUV's put their orfice tube on the outlet side of the condenser, right below/in front of the radiator.
It is under the vacuum brake booster on the drivers side. Gm manual calls for removal of the booster to ease access. Alot of work for a 5 dollar part.
