On our way to Austin Texas in the morning, the AC was too cold and I adjusted the AC level knob to less cold and it stuck in hot air. On the way back to San Antonio with outside temperature at 84F, it was intolerable and we had to keep the window opened on the highway for 1.5 hrs. It was really bad.

THE AC SEEMS ONLY TO WORK OK ON COOLER DAYS, ANY TEMPERATURES OVER 85 DEG., FORGET IT - THE AC IS EITHER TOO SMALL FOR THE CAR OR IS UNDER CHARGED OR SOME OTHER PROBLEM i.e. BAD COMPRESSOR, REFRIGERANT LEAK. SOMETHING. DOESN'T WORK WELL IN THE HI-DESERT. I HAVE HAD NISSANS IN THE PAST AND I NEVER HAD SO MANY ISSUES.
