Sorry, but I've never been much of a car guy. With that said...I was driving around tonight and the fan for my heater suddenly started slowing down to the point of nothing. I turned the dial for the fan all the way down, waited a few minutes, turned it back up and the fan was blowing full tillt. But after about a minute it did the same thing...went down to nothing. I tried it a few more times and the same thing happened over and over. Oh yeah.....as ithe fan was slowing down I could hear what sounded like a low, grinding sound. Not real loud, but just enough where I could hear it The car is a 2005 Ford Focus. Again, I'm no mechanic. Is this a hassle to try and fix myself? Any suggestions? Thanks in advance.
