The orifice tube on a 2004 Ford Freestar is located
within the A/C high-pressure line. It's not a separate, easily visible component like a filter. You won't find it just hanging out somewhere. To access it, you'll need to locate and disconnect the high-pressure A/C line. It's usually near the compressor, but the exact location might vary slightly depending on specific Freestar model variations.
Because it's integrated into the line, replacement typically requires replacing the entire high-pressure line, not just the orifice tube itself. It's a job best left to an experienced automotive technician with proper A/C handling equipment to avoid refrigerant leaks and damage.
