Sometimes creative thinking is necessary to resolve
a stubborn A/C issue.

ith your patience, I am
going to deviate for a
moment from my normal
approach of explaining
how to choose and use the right tools
to complete a task. My approach
this month is a little personal, but
trust me, it is relevant to auto repair
and the systematic approach we
should all take when diagnosing and
repairing vehicles.
My wife has been fighting a degenerative brain disease for a little over
two years. We have been to numerous
doctors, who have performed countless
tests, only to be told repeatedly there are
more tests necessary. Keep in mind, this
is a degenerative disease, meaning the
longer things go on without the proper
diagnosis and treatment, more and
more serious symptoms develop.
Not only have we spent innumerable
hours and thousands of dollars going
back and forth with the doctors, but the
frustration of dealing with an ongoing
issue takes a mental toll and causes a
mistrust of everyone involved in the
diagnostic process which, by the way,
directly relates to automotive repair.
Finally, we found the right doctor
that not only has enough experience
with this exact type of condition but
has also had success in performing some
non-traditional tests to help diagnose
her symptoms. Not only did this doctor
have the proper test equipment, he also

with a treatment plan to manage - but

I am telling you this to explain
a simple fact: whether diagnosing a
vehicle or a person, having the most
up-to-date and relevant tools, combined with your experience, is essential.
Additionally, having access to the most
current information and knowing how
to use that information will allow you
to be more efficient and accurate with
your diagnosis.

We will come back to the correlation
of a doctor and a technician shortly, but
for now on to this month's topic: air
conditioning. A/C systems have been
on vehicles for approximately 80 years.
In that time, they have gone from an
optional extravagance that could be
added on at the factory or in the aftermarket to being standard equipment on
most cars sold in the U.S.
It is also important to keep in mind
