Actually, I'd love to know why, but at my previous place of employment, no
one was able to explain it to me. I was eventually left with the fact
that it occurred and that to check the system, I should fully charge it
and recheck for the condition.
One of the things that makes me unusual as a technician is that I have a
better understanding of how the vehicle actually works and the ability to
determine what malfunctions might cause certain symptoms by using logic.
This one, however has left me stumped. I've been able to come up with no
logical reason why it should be so.
Lastly, I fully agree that communication, knowledge, and understanding are
critical to customer satisfaction. As the original poster has not yet
replied, I'm left wondering whether the dealer bothered to explain to him
what was wrong with his a/c compressor and why that caused the need for
replacement. If there indeed was a necessary reason for replacement, then
this communication would have helped the customer understand that there
was a separate problem.
While in my case the advisor may not have been able to relate why the
refrigerant being low would cause poor cooling on one side, he would have
had the information that the condition was remedied by charging the system
to the proper level and that I had or had not found a leak and the
location of such a leak. These would all be important items in the
customer's understanding of what repairs were being done and why they were
I agree that in this case there was likely an error, but I don't know
enough facts to feel comfortable about my judgment.
