    I was driving the other day when all the sudden my blower fan randomly turned on with none of the controls on. This has happened once before it only flickered on and off for about a minute but this time it stayed right on through to drain my battery. I pulled the fuse out and started it up, it was idling slower and slower until it eventually died again. I have the battery from my truck out and charging for the night. Any suggestions?
