I was on a long road trip and had my stereo on, and forgot that I was running my fan at full blast. About 6 hours of driving later, after having the car off maybe twice for short periods of time, I turned my music off and realized my fan was no longer blowing. My buddy tapped on what he thought was the fan motor under the glovebox, it sounded like it was trying to start back up, but it didn't and only has started back up a couple of times inconsistently. Any suggestions on what's broken.
