I'll remind you again that an orifice tube will not have a problem unless the system is contaminated and if you don't resolve the source of the contamination, your subsequent repair cost will be astronomical.
This particular vehicle doesn't have a replaceable tube. The tube is built into the liquid line that runs from the condenser to the evaporator and the entire line has to be replaced. The only way to see the tube is to cut the line open. Just the fact that your mechanic doesn't know this tells me that he is not experienced in AC whatsoever. I'm a tech in South Florida and I have specialized in A/C repairs for many years and do these every day.
