Hi. I have a 2012 Nissan Armada. Condenser & compressor are about 7 months old. Just changed cabin filters two weeks ago. AC flow was much better, but as of two days ago, it is blowing hot air. I went to mechanic, he put gauges on and said I was low on Freon. I bought the UV dye and Freon and dye didn't reveal leak. However, after he added Freon and I started driving, I heard a loud sound as if someone was letting air out of tires and the air went hot again. I went back and he said condenser fan is showing it is receiving no power. I've done some research and bought a condenser fan relay from parts store today. Does anyone have suggestions or any similar experiences or fixes?
