can evac and recharge of an a/c system help w/possible leaking evap core

Thanks for the info...I was afraid of that. Much appreciated!

One thing that may help, if it hasn't been done yet, is adding some uv sensitive dye so the leak can be found more easily using a uv light .. 'IF' the 'evaporator' is leaking, dye should show up in the water drain when a/c is on .. Good luck with it!
