I started my car this morning and couldn't get the fan to turn on at all. I kept messing with it as I was driving and eventually it came on. I noticed that it wasn't blowing as fast as it normall would blow and when I got to work I noticed that there was a clicking noise coming from under the glove box which I'm assuming is the location of the fan. It sounds like it might be a motor going bad but I'm not sure. Sound like that's the issue?
