Where is the ac orifice on 2002 Nissan Frontier V6?

On a 2002 Nissan Frontier V6, the AC orifice tube is located in the high-pressure line between the condenser and the evaporator. You can find it by tracing the line from the condenser, which is situated in front of the radiator, towards the firewall where the evaporator is located. It's typically housed in a metal fitting and may require some disassembly to access. Always ensure the system is properly evacuated before attempting to service the AC components.
