I need some help

Here it goes. My heater and ac work it just i get no air blowing. I hooked the blower to a constant 12v it blows. I read about this blower module that it could be the problem. I went to 3 part stores and they had no clue what a blower module was.

Does anybody have the part number for the blower module?

Does anybody have a pic of it?

Thanks in advance

The manual don't give a pic. but says it is behind RH side of I/P, near blower motor. And another paragraph, says it is located near the blower motor, and is mounted to the side of the HVAC module.Which is behind the center of the I/P. Not much help I know.
