Thanks Tim for the excellent points. Both you and Fred are right that I need
to locate the leaks first. A few other things that I need to clarify before I
go ahead with the job. The AC system was injected with tracking dye about 4-5
months ago when the previous owner refilled it with freon. Now the freon is
gone again, should the tracking dye still be visible? If I just want to
expose the evaporator assembly and other area to inspect for leaks, do I have
to remove and lower the evaporator from the top back of the van? I am not
sure about what you mean by remove the cover over the A/C relays and high
side fitting in the rear closet. Would you please explain it a little more
detail? Thank you again for your help.
