I went into the shopping center for about twenty minutes, upon returning to my car I noticed fog on the inside windshield, once I opened the door I heard the blower motor going. I woke up the next morning and my battery was completely dead. I didn't know it until today but I have had FSU issues since last summer. The a/c would just cut off and no matter the setting it wouldn't come back on until it wanted to, I never thought to look it up as the a/c would always start to blow again before the end of my trip. Know on to the question, Have we gathered more info on the best FSU to purchase someone point me in the right direction or should I just go to my dealer?
