Hi there,

If it is leaking from the evaporator, I would find a work shop that has an electronic refrigerant detector, this will pick up any traces of refrigerant on the cabin, under the dash and in the vents, you will need to park re charge the system to do this test, start here.

Not sure where yours is leaking from but, make sure you replace the valve cores on both the " High" and " Low" side before re-charging the system.
Had a guy at work (he did HVAC work on the side) tightn mine up and it worked for a year or so, but then I had to re-place the valve core(s).
Think I paid 3-4 dollars for the asortment pack at the parts store. Very cheap investment for when its 100 degrees outside.
