The orifice tube on a 2003 GMC Envoy is located in the liquid line of the air conditioning system. To access it, you'll typically need to follow the line from the condenser to the evaporator. It is often found near the firewall, between the condenser and the accumulator. Ensure the vehicle's AC system is depressurized before attempting to locate or replace the orifice tube.
