Cooler Weather ... Finally!

Although I don't think it's going to last, today is a nice respite from the heat. It got down in the 50's last night -- great windows open sleeping weather, which is exactly what I did. But it's supposed to be back in the 90's by the weekend. Which is bad for two reasons, one I hate the heat, and two the air on my car is acting wonky. It will work, and then I'll go in the store/home/work whatever, and when I come out it won't work. I think it may be a relay switch .. boy it sounds like I might actually know what I'm talking about .. when in reality I know NOTHING about cars.
