Hi there,

A few days ago I asked about my evaporator freezing, wondering if it was
the switch with the capillary tube that is inserted into it.  I got some
different suggestions so today I spent a little time with it.  I checked
the evaporator fins to make sure they were clear (they were for the most
part but I cleaned them a little more), then ran the ac while right next
to the evaporator.  Almost instantly a bit of moisture formed on half of
it.  This continued to form until the moisture slowly began turning to
ice.  I could hear the switch right there cycling on and off but it is
located in the half of the evaporator that was not icing.  I took a
quick drive and I could tell that the switch was cycling on and off when
off things would begin to melt, when on they would freeze up again
(freezing a little bit more area each time), all the while the section
of the evaporator where the capillary tube goes in never even developed
moisture.

Any guesses?

Oh, I also gave a quick visual inspection of the rest of the AC
components while it was running, everything looked normal except for the
receiver/drier site glass where the color was orange (is this my
problem?).

Thanks for your help
John
