WTF does Max A/C do?

Dude I'm a service engineer for a car company...and have worked with car companies since I was 22. If I know anything in this world...it's cars. You guys just guess at shit...or try to analize things using general common sense. Your original statement that the compressor cycles because of "Max A/C" or "Normal" just is not true.

Those that have Max AC and a Recirc button is simply for air venting direction (Max AC) and then % outside air using the Recirc button.

So two decades in the industry and you think GM builds a quality product and think cars have either a Max AC button OR recirculate. And I'm the one that doesn't know what he's talking about.

All cars I've driven have both. All cars I own kick on the auxiliary cooling fan as soon as Max AC is selected. Observation skills bordering on retarded should still allow you to at least gather that if cars have been your life for 22 years. If I was wrong about the compressor, so be it, I'm not opposed to learning from someone here. Provided they at least come across as knowledgeable, beyond just claiming to be while regularly showing otherwise.

It doesn't matter that is SAYS MAX AC, what matters is what it does. FWIW, my 2011 Mazda 3 has both, but the MAX A/C does nothing but ensures that the Hot/Cold is all the way to the full Cold. The condensor fan runs whenever the A/C is turned on regardless if it is all the way to the Max AC position. The Recirc button does just like it says. Recirculates. Why they even put "Max A/C" I can only guess is so the clueless don't leave it still in the "blue", but not all the way in the full blue range. Ford, GM and Chrysler always used only Max AC, which forced recirculation.

...All cars I own kick on the auxiliary cooling fan as soon as Max AC is selected......

Well, apparently you have not driven a GM, VW or Mazda because they don't. The A/C fan on all GM vehicles was always a function of the A/C relay ON and A/C high side pressure. I would be that Max A/C does not even have a signal to the body controller. My Mazda 3 runs the A/C fan when the A/C is on and the A/C high side pressure is above a certain threshold. Max AC is not any type of input.

So now the question remains....do you have BOTH a recirc. button AND a MAX A/C button? Or do you have a Recirc button and lettering that says Max A/C because then Max AC doesn't do anything.

I should have said that Max AC acts as a recirc function if you don't have a button. If they put both there, the MAX AC is only to make sure you put it to full cold.

Little disappointed it wasn't an MX3. Lil 1.8 V6 was entertaining back in the day.

What happened to the Golf? And the Geo or whatever it was? Dude you must change cars like every 6 months.

It was a lease.....I sold it to CarMax (yeah I know) and they gave me 1900 bucks more than I owed on it after 15 months of driving it. I put 995 out of pocket on it and it was 200 a month lease.

This Mazda was 999 down and 199 a month. So...I sold the Golf, put the 995 down, kept the same payment and bought 3 sets of race tires with the 900.

I sell cars when it's profitable. You just have to know when to sell and be forceful at what cost the cost vehicle needs to be.

bzzzzzzzzt- sorry, but thanks for playing. Tell him about his fabulous door prize, Al!

(just selected "MAX A/C" and turned the Temp into the red zone and, woe and behold, hot air came out)

Not trying to bust your balls (okay, maybe a LITTLE) but not all cars function the same way.

Are you just acting stupid? You just turned the heater control knob to full hot. No shit it is gonna blow hotter when you turn it all the way hot. But do you need a label that says "Max AC" to tell you that putting it all the way cold puts the door vents fully to the evaporator? Is it not obvious? The answer is NO. My point is the label Max AC does nothing IF you have a recirc button.

Would you like a Max Hot label too?
