Upgraded from 09 base to 13' nismo... A/C Issues
 

My experience since switching to an base non-sport to an new nismo has been mostly awesome... except this issue that's bothering me.

The A/C is switching from recirculate to Vent by itself on a daily basis. I live in Puerto Rico and average temperature is in the 90's. Theres no reason at all for the a/c to switch from recirculate to vent by itself unless I selected an temperature higher than ambient, dash temperature seems to be sensed correctly, has anyone experience such a behavior??

I want to have some input before heading to the dealer, they are aren't very useful usually unless pointed directly at the source/documentation.:shakes head:

I wish I knew what was causing this issue..

But my guess is that your "air button" has a short in the electrical system..
You could technically take off the dash paneling and check the connection to the A/C module. (Takes 3 minutes)

I bet its just a bad circuit though! Bring it to the dealer & tell em to replace it. Thats all
