With it all happening at the same time it could be a common problem. Maybe there is a short in the multi-function switch that's messin with the blower. I keep refering to the m-f switch cause mine did something similar with the signals and wipers and that's what it was. If you could get one off another truck to try and see if that's it before buying one would be the way to go.
