<< I have a 1985 Westy with the A/C unit in the rear.  Today my mechanic
 checked the temperature of the air coming out of the vent and told me that
 it was about 60 degrees.  This is after I have spent close to $1000 at the
 dealership to get the thing completely fixed -about a month ago.   This
 included a new evaporator-the last one in the US-and a recharge.  My
 mechanic seems to thing this is about  as cold as it is going to get.  My
 question is: Is this reasonable?  What would be a reasonable temperature?
 What can be done to decrease the temperature that does not cost a fortune?

Hi John, it should be cooling between 40 to 48 degrees, depending how hot it
is.  Your tech should be seeing a pressure on the high side of about 150 to
275 lbs, and on the low side about 25 to 40 lbs. If the pressures are even,
then you need an expansion valve, 4 hrs labor plus parts.  If the pressures
are good, then with a small pin light check what color the freeon is inside
the sight glass of the reciever drier. If it's rusty brown color, than you
need reciever drier.  If you are going to replace the drier, than this would
be the time to convert to R134. It will be cheaper to convert than stick with
R12.  Let us know what happens.
