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?

TIA,
