i just installed a headunit in my 07 350z. the a/c works, but whenever i turn on the ac, the climate control would switch over to rec. air and when i turn off the ac, the climate control would switch back over to fresh air by itself. i've checked all the wires and everything seems fine. do you guys think i messed up the white ribbon that connects to the ac controls? do any of you guys know whats wrong?

 

Hum,,,I am trying to think of my 06 does this? I think it does. If I have my AC on and its on REC, and I want fresh air,,,I just push the button. I know the AC works best with the REC on......I will check it out today and post my results this afternoon. Again, I think this is normal.

 

im new to the z myself but as far as i know when u turn on the ac esp on an import it goes automatically onto rec that works the best and pumps the hardest unless it's raining then it goes to fresh because u want fresh air circulating in the car otherwise the windows fog up.

 

Yes,,,hitman1613 is right. I just went to the bank, turned my air on and it went directly to REC. So, Steven37, I think your A/C is fine... If you get a chance,,post photos of your headunit install...I always enjoy new photos.

 

This is normal operation.

 

but what im asking is, is it suppose to switch back to fresh air by itself when you turn off the ac?
