Which way is the orifice tube supposed to go in the evaporator inlet tube? Is the long end supposed to point toward the drivers side or toward the passenger side? I've been reading various a/c write ups online and I'm confused now as to how the refrigerant flows in this system and how everything is supposed to be oriented. The orifice tube has an arrow molded on the small end that points toward the small end and away from the long end. The one I took out came out of the evaporator inlet small end first with the large end pointing toward the driver side and covered with debris. Is this the right way? Is there a flow chart anywhere specific for this system so I can better understand?
