if i have a manual fan (AC/heat) can i change it to an automatic climate control?

 

I believe so, but parts alone will cost you a fortune, check with a dealer. Good luck.

 

what I kinda meant is that just by changing the center console itself with an automatic climate control, would it work?

 

No, on top of the console, you'll need sensors + other electronic controls for heat and AC. Auto climate control is nice to have, but retrofit costs way too much. Compared to manual controls, it might just cost Mazda $200 more at the factory to put in auto. I bet it will cost you at least $1,000 just for parts to changeover.Use you hand and save that for some performance upgrades. You bought the car to drive, right?
