with the AC running, grab the AC lines and note where the temperature changes from hot to cold (normally sweating). The location of the temperature change is where the orifice tube is located as the freon transitions from a high-pressure gas (hot) to a low-pressure gas (cold)

That is a good idea unfortunately my AC is not currently running because of loss of freon. Seems like on cooler days I can get it to come on sometimes. Dye was put in it and it is showing up at all connections

O'Reilly Auto shows the line below as what you need to look for and replace.

Close, the refrigerant transitions from a high pressure liquid before the metering device (in this case an orifice tube) to a low pressure.
