Re: Smoke started coming out of my vents (blower motor, relay, fuse???)

The vacuum leak is likely the "winding sound" you described.

Seems that is correct. Blower motor works on all settings, but is stuck on that defrost position seems to be the only one.

Can i leave it in that position? As I have another issue that I needed to address prior to this mess: the heater core (or lack of heat at least) that I need to deal with before it's 1 degree outside here in Minnesota.
