‘88 5000s Climate Control - How cold is COLD?

["AMZ" <amz@eskimo.com>]

Thanks to everyone for their replies to the first question about a/c blowing
lukewarm air.  It brings to mind, however, the question, "Just how cold
should COLD be?"

As a test, I backed out of my relatively cool garage and put the a/c on LO
(Auto).  The outside temp was 70+.  For the first few minutes, at least, the
air was a pleasant spring breeze.  After a while, however, it just blew at
"room temperature."

For comparison, our '94 Jetta GLS becomes quite cold after running the a/c
on full blast for a while.

Am I just spoiled by a newer-technology a/c system?
