Your friend broke something. ;)

First step is to figure out if its a mechanical or electrical problem? Can you hear the fan running when you set it and no air comes out? Or does nothing happen?
The heat used to work now it doesn t blow, it comes out only with defrost but slightly. The computer says its coming out with the fan showing it blowing but no heat. The car says electrical problem how do I fix this?
