True enough. I reference high side and low side to the ports, high side is red and low side is blue. On this unit the blue hose ( low side hose) hooks up to the port welded to the accumulator. The red hose ( high side hose) is welded to the line upstream of the orifice.
It took the pressure drop at the orifice then enters the evaporator and exits the evaporator to then enter the evaporator dryer/accumulator. I guess I meant the leak is at the entrance to the evaporator, which is upstream of the low side port.
