Recardo,
I said my AC "was running out of Freon", not OUT.  I have no idea what
caused
the situation, but I did observe my mechanic the entire 15 min. he worked  on
it.
First, he removed some panel exposing the ac (evaporator?) and checked  all
around and concluded that the drain hoses were fine [caveat:  when I  had my
engine
fire over a year ago it melted all those hoses then, so the mechanic had
replaced
them all back then--thats why he probably was quick to conclude that it
wasn't the
hoses]  Then he recharged the system and I have been driving with AC  on ever
since
with no problem.  You have to BELIEVE IN MIRACLES :-)
