My engine cooling fan in my 95 SC will not turn on weather the air conditioner is on or not. My engine temp stays normal when I'm driving around and the air is moving but when I sit in traffic or just let it idle the temp just continues to increase and the fan never kicks on. I don't know if there is a few common things that cause this to happen or if there is another tread explaining this that I could be directed to. Any help would be greatly appreciated.
