How to locate the blower motor and resistor?

Hi. Can anybody please tell me where to locate the blower resistor/fan control module. I think it's defective. If somebody can give me an hint it would be great. It's about -2 C outside and snow. It's he automatic temp. Regulator on it, the big knob on the left, the AC light can be turned on/of, checked the fuses under dash, and in engine room. If anybody have an electrical diagrams and/or where located I would be very happy.

Thank you in advance.
