While driving my 5th gen around town I noticed my air condition started to get warmer and warmer. I then checked my temp gauge and the needle was up pretty high! So I turned off the "condition" and the needle lowered but went back up again and then it would go down and up again. So I pulled over and checked the coolant level(fine), oil(fine), belts(fine). I then tried to crank it and it wouldn't turn over and the battery is only a mth old. Please help!
