2004 Chevy Malibu A/C and Rear Defrost and Recirculate wont

After doing a little reading, it looks like those cars have problems with the climate control head (part in dash) whan they start losing different and unrelated systems like a/c and recirculate. There arent any seperate fuses for just those functions.I also see where they have problems with the Body Control Module, but that is when the lights/buttons are all working and it just wont turn on the a/c
