Sampler blower motor ?

[cil254]

W202 / '94 C220

I have this high pitch noise coming out of the dashboard around the passenger side when the climate control is on. I did some research and I suspect the blower motor. I'm planning on taking it out and giving it some lube.
I found out the noise can also come from the aspirator/sampler blower motor on certain cars. My question is: Does the W202 have a sampler blower and if yes, where is it located ?
