The entire heater box, all actuators, and the dash wiring harness would need changed, which would require the purchase of said components and complete removal of the dash to install. Still want to try it?
I have the dual zone auto air . . . I personally wouldn't waste my time/effort/money. It's a "nice" thing to have, but totally pointless in my opinion. My passenger often will increase/decrease "her" side by 1C - I mean, you wouldn't even notice that! It's either on or it's not.
My biggest beef is the poor quality of air flow when I just want air flow from outside. Always need to crack one of the back windows or the roof to allow for the air to draw through the vents.
My advice - invest your time/effort/money into other areas of mods.
It's possible, yet that would be a pretty expensive change. If you are ready to spend some money on the conversion, we have all the components required. Check out our wide selection of A/C Control Units and feel free to ask away all the questions you have. We will be glad to help you.
Saddened by this. I came from car with fully auto climate control and it was wonderful. Hate not having it now, and have vowed to never buy a car w/o again! You set the temp to what you want, and you never have to adjust anything again. Ever. Summer, fall, winter, spring, get in an drive and it's just what you wanted. I find having to adjust fan and heat 3-4 times each per drive to be a safety issue too, constantly fiddling with dials when I would rather have my hand on the steering wheel!
