Diagnosing today’s climate control systems: What NOT to do!

By Jim Taylor, Editor MACS ACtion Magazine

Introducing more of the teachers and leaders that will be presenting classes at the upcoming MACS Training Event and Trade Show in February. Each of these class leaders has been chosen for their detailed knowledge of their topic and their ability to present it to you.

Peter Orlando

Peter Orlando, Automotive Training Technologies

“Diagnosing today’s climate control systems: What NOT to do!”
and  “The ’99 Expedition electrical experience”

Peter Orlando is a 31-year ASE certified Master Automobile Technician with additional certification in A9, L1, L2, T6, and T8. Peter is a MACS-approved instructor, a certified New Jersey emission repair technician, an approved training provider in NJ, and a licensed motor vehicle inspector in New Jersey and Pennsylvania.
If you’ve never taken a class with him, you’ve missed a lot. Peter combines his extensive, hands-on shop knowledge and experience with no little bit of humor and big city sass. Hey, what’dya expect from a guy that plays drums in a couple of rock bands?

We asked Peter to explain his class content in his own words, as if he were speaking to a prospective attendee (that’s you).

“Hi … pleasure to meet you. I would like you to think about the most difficult time you ever had about fixing a car. While there are many different reasons a mechanic might have difficulty in troubleshooting a problem, it generally falls into two categories – lack of training and technician attitude!

In my travels , I find 90% of the time the mechanic-technician lacks the ability to think through a process…consistently. My seminar is going to educate you on how to think about the problem, how to use deductive reasoning and critical thinking skills to address the problem, and understand why it has to work the way it was designed. Education is a change in behavior! Unless there is a change in behavior, no education is taking place. I choose to teach awareness of ‘What DO you Know’  vs  ‘What Don’t you Know?’

I will tell you this: after sitting through my seminar, a technician will have a different way of thinking through a problem. You’re here at the MACS convention because there is a need – in fact, a requirement – to be better at what we do. When you return back to the shop, I will hope to hear from you that what you learned in our class changed your way of thinking about a problem forever!

Think about it; you can walk up to the boss and say, “Hey, I need an A/C compressor for the Sebring,” and when he asks why you can answer with confidence,  “Because based on my tests, electrically, everything is satisfactory. So there is a mechanical problem with the compressor.”  Change in behavior!

I’m Peter Orlando, and I approved this message. “

Don’t say we didn’t warn you; both of Peter’s sessions are well-worth your time.
