Saturn SL1: Bad relay or bad fan motor?

I have a 2000 Saturn SL1 that is overheating only when the AC is on and only when idling. Can anyone tell me where the relay is located for the electric cooling fan motor, and also where the fan motor is?

I was told once that my car has two fans. Does anyone know the difference between them and where the other fan's motor and relay are located. I did a search for parts at Autozone's website, and came up with only one option, an electric cooling fan motor and relay.

I'm kinda strapped for cash and was hoping to be able to fix this myself. How complicated is it to replace the electric cooling fan motor on a Saturn SL1? I used to work on an old Torino I had all the time, but this car is a whole lot different. Would this be simple for just about anyone to fix, or should I have a mechanic do it?

Thanks!
