need a wiring diagram for 99 grand am

I need a wiring diagram for my 99 Grand Am. My heater/air completely quit working the other day when I went out to start the car. My husband has tried like everything(the blower motor, the resistor, I even went out and bought the fan speed switch) none of this has solved anything. I was going to go get a manual today but it is snowing. I do not know anything about this wiring stuff so I hope that this is the diagram I need. So if anybody can please help me it would be tremendously appreciated.
