Freshen Up Your Musty Interior
By: Bob Freudenberger
Saturday night, and you’re ready to prowl. You flip on the a/c only to have the passenger compartment fill with the sweet aroma of old sweat socks as the dash vents pump in cold air. Get to the bottom of the problem, find the source of that nasty odor and kill it.

Evaporator Odor – What to Do Now?
By: Paul Weissler, MACS Technical Consultant
The customer turns on the A/C, and for a minute or two
there’s an obvious “dirty socks” odor. Straightforward
problem, it’s evaporator odor. Well, probably, but not
necessarily. Even if the odor really is caused by a fungal
growth in the evaporator case, applying one of the popular
disinfectants may not be the whole answer.

Common Air Conditioning System Problems
Air conditioning odor is a common problem that plagues
almost all vehicles at one time or another. The first step
in treatment is to find the source of the problem.

Air Conditioning Systems
By: Laura J. Rose, Robert B. Simmons, S.A. Crow, and Donald G. Ahearn
Methods to reduce or eliminate the moisture retention in the
automotive air conditioning system, coupled with less
susceptible or antimicrobial substrata, would seem the most
practical means for controlling microbial-associated VOCs.

Compressor Warranties Get Tough
By: Jacques Gordon
If a new compressor is part of the job, check the manufacturer’s or rebuilder’s warranty carefully before closing up the system for evacuation and recharge.

The most common cause of a compressor failure is inadequate lubrication, and more.

A/C Triage – Ensuring Replacement Compressor Survival
Over the past several years, ACDelco has reviewed, inspected

can be grouped into four basic modes: lubrication,
refrigerant, debris and product defects.

A/C Compressor Survival
By: Greg McConiga
When it comes right down to it, there aren’t all that many
things that can go wrong with an air conditioning system.
So, what causes a compressor to come apart? Lots of things,
so here we’ll discuss some of the conditions that can turn
and expensive compressor into scrap metal.

Common Air Conditioning System Problems
Most of you know that the single biggest reason for
premature compressor failure is debris left in the system
from a previous compressor failure. What you may not know is
that even a good flushing cannot remove all of the debris.
Automotive Cooling Journal, March 2001
ACJ3.01.pdf
Replacement A/C Compressor Failures – What to Do?
You send out every replacement compressor job with fingers
crossed hoping that it doesn’t come back. Of course, you use
the best quality new or remanufactured compressor. You
routinely replace the accumulator and orifice. When the
manufacturer recommends it, you flush the system before
installing the replacement compressor. You even close the
A/C connections with tamper evident seals. Still, you see
replacement compressor installations come back prematurely.
Action, May/June 2001

Compressor Failures: Causes & Cures
The 2001 MACS convention’s compressor panel certainly nailed
the debris problem – you’ve got to get it out of the system
or somehow trap it so it doesn’t get into the new compressor
and cause a repeat failure.

The Hot News in A/C Service
By: Paul Weissler
According to the latest MACS survey conducted in 2000,
compressor replacements account for 52% of a/c repairs,
compared to just 23% to 29% in prior years. As a result,
manufacturers and remanufacturers are shipping more
compressors to distributors, who are selling more to
jobbers, who are selling more to shops, who are installing
more of them in customers’ cars.
Motor, September2000 Motor092000.pdf
Top 20 Tools Award
By: Paul Weissler
When an a/c compressor fails, debris inevitably settles in
the suction side of the system. And even after thorough
flushing, some is likely to remain. That’s why so many
replacement compressors get trashed.

Universal evaporator dryer module now available

There’s finally an evaporator dryer afterblow module that
works on all vehicles. Oh, you’ve been installing evaporator
dryer modules? Sure, but the so-called aftermarket universal
one worked only on HVAC systems with power side switching,
and many systems have the switch and blower control module
(or resistor) on the ground side.

The Increased Threat from Sealant
By: Frank Walker, AirSept VP of Marketing
Air
conditioning repair specialists can expect more backyard
mechanics to turn to sealants in an attempt to avoid the cost of
professional repair as the price of R134a continues to rise.
Sealant is available over the counter at auto parts retailers
and mass merchandisers, and is packaged in a variety of forms.

Skyrocketing R-134a prices increase the threat of contamination from alternatives
By: Jay Sicht
If you
haven’t had to purchase refrigerant since last year’s cooling
season, you might be in for a shock. The price of R-134a
refrigerant has gone through the roof this year, and the fallout
from the price increase, air-conditioning personnel need to be
wary of practices that could harm equipment and their
refrigerant supply.

A/C Triage — Ensuring Replacement Compressor Survival
Of
importance to technicians with this recovery is protection of
their expensive recovery equipment from sealant. There are no
tools to identify all the sealants employed in the automotive
aftermarket. Therefore, the use of a sealant protection device
or sealant detector prior to running the recovery equipment is a
worthwhile investment.

If everyone who serviced a
