THE AC SYSTEM HAS NEVER WORKED PROPERLY. THE CONTROLS CHANGE FROM ONE SETTING TO ANOTHER WITHOUT YOU PROMPTING CHANGE. IT BLOWS HOT AIR WHEN ON COOL.. THIS HAPPENS REGARDLESS IF YOU ARE SITTING STILL OR TRAVELING AT ANY SPEED. THE CONDENSER WAS REPLACED AND THEN THE DEALER REPLACED THE "O-RINGS" AFTER THAT AND ADDED FREON. .. ONLY WORKED FOR A WEEK BEFORE THE AIR QUIT WORKING AGAIN. I BUY A NEW CAR EVERY 2 YEARS AND AFTER THE PROBLEMS I'VE HAD WITH THE AC AND LACK OF SERVICE FROM THE NISSAN DEALERSHIPS , THIS WILL DEFINITELY KEEP ME FROM PURCHASING ANOTHER NISSAN. THIS IS A COMMON COMPLAINT WITH THIS YEAR/MAKE/MODEL VEHICLE AND NISSAN DOESN'T WANT TO TAKE THE RESPONSIBILITY TO REPAIR IT.
