Where is the orifice tube on a 1995 suburban?

On a 1995 Chevrolet Suburban, the orifice tube is located in the air conditioning system, typically within the liquid line that runs between the condenser and the evaporator. To access it, you may need to remove the dash or some panels to reach the evaporator housing. It's usually found near the firewall, in the engine compartment, or close to the evaporator core. Make sure to discharge the AC system safely before attempting to replace the orifice tube.
