Ac/heater & rear defroster not working

[bimmerr]

Hey guys,
Something really weird just happened yesterday on my 96 328I. My AC,heater and rear window defroster stopped working all at the same time. I can hear the blower kicking on but it just doesn't pump out anything. I also noticed that when i tried to put on my rear defroster, it didn't work either. I have checked fuses but quite not sure what else to look at. Has this happened to anyone? If anyone could help that would be great. Thanks. I really just need the heater and defroster to work for now since its getting cold out. I will deal with the ac once it starts to get warm out again. Please help

Not 100% familiar with how the electronics are setup with the heating and airconditioning, but perhaps you have a bad relay?

I found this website perhaps it will help you.
