Air sampler motor over driver's head

Does anyone know the part # for the little air sampler motor over the driver's head? I hate to pay straight price to GM for this.
thanks if you can help. Oh, 2001 Suburban 1500

What is an air sampler motor, and what does it do?

The air sampler motor may not be called that specifically. It is over the drivers head, there is a small button with holes in it and I'm told it samples air for the air conditioning/heating system. I suspect it just measures the temp but not sure.
My daughter had one of these replaced recently, the bearing is going bad in mine and it rattles above your head. The little fan is above the headliner. I just can't find the part #. Interesting the complexities of these systems.
