So, living in texas where we're seeing 105* daily has made me wonder something.
My car is equipped with remote start, and i leave it on it's highest setting so when i make the trip from my desk at work to the car, it's the coolest it can be.

Sadly, i still have to toggle the max a/c when i get in the car. Is there a way to have it set by default to remain on max (if max was turned on when the car was turned off) so that i can have it cooling down much much more before i make it to the car?

Would this be a mechanical switch, or possibly something that could be done in a tune?

 

The Recirc switch is a momentary switch in the A/C control head. So not really a mechanical switch that you can just leave on or rewire.

If someone bothered to crack the programming on the control head its possible they could change that... but its highly unlikely that this will happen.

 

The difference between Normal AC and Max is Recirculation.
The Max is re-using the air inside the Cabin and Re-Cooling again and again, thus it gets colder faster.
But, when you leave your car for hours in the heat, the air inside is Much, Much hotter than the air outside, even at 105+ Degrees.
I would think they set the system up this way so that the AC can cool the cooler outside air and thus, provide more economical and faster AC.
I'd just remote start the car, let it cool off and when you get in, switch it to Max AC as it was designed.

 

I've actually found that using recirc immedeatly after starting the car will cool it off faster than using outside air. Something I've learned in the many hot summers I've endured down here.

 

No ****.
Not to mention i use it for a few minutes before getting into the car.

Oh well, i'll continue my search.
