Default A/C and Heater not working

what would cause both the A/C and heater to not work? I first thought that I had just an A/C problem and people suggested that my compressor was bad, but now that it is cold I have found that I don't have any hot air coming out when the heater is selected either. I can feel the heat, but there isn't any blowing. I guess it could be the blower motor but I am not sure. Also, does anyone know where the blower motor relay is located? That is a simple component to check out and replace if that is the cause. Thanks in advance.

My guess is blower motor OR the actual climate control switch. Blower motor should be underneath the passenger side of dash.
