Is Max & Recir same function - 93 k1500

[jus10inbrla]

As noted. What is the difference between the two? Was it recir until 91 and then 92 swap to max just because ? Any “‘mechanical” difference. Mine currently has the max . But say i find one with recir instead. Does anything have to be repinned. Rewired, etc

The heads with dedicated recirculation buttons are all wired the same. If you get one, it swaps right in. And if the replacement head doesn't work, just take the face off and swap the buttons themselves.

Ok cool. So ; any idea why GM decided to rename thr button ? Lol

Maybe to get people to press it less for fuel economy? You dont need MAX mode if its only 80 outside but you could leave it in Recirc mode without thinking twice.

It takes less letters which fits better on the button

Why AMC's Cars Used To Have A 'Desert Only' Mode - The Autopian

The vast majority of cars on the market have very similar controls. Indicator stalks, accelerator and brake pedals, and volume knobs all used to be fairly standard across the industry. What really lights up our dopamine receptors as enthusiasts are when we find something on a car we’ve never...

It looks like the Destert Only mode was for real. That setting runs the compressor 100% and it needs the hot dry desert air to keep the evaporator and condenser from freezing over.

I use the MAX mode frequently in the hot 95*+ , 98% humidity in S GA summers. I noticed when I use it, the display says recirculate or at least an abbreviation thereof. I assumed it was the same thing. I just figured with that much heat and humidity the system works a lot less using the cabin air than cooling the ambient air outside. I assume that good logic, right??

Yeah,I do the same for the same reasoning. Mine says RECIRC. If it gets too cold inside I turn the blower down and crack a window.
