Blower motor on w116 300SD - Fried?

[bmonk]

So on my way to the coast last night, about an hour into my trip, I began to smell something coming through my vents. I pulled over first chance I got, and realized my blower motor was not working. I should mention that I believe my evil servo has been "bypassed" since I have no control over temp, just fan speed and direction, as in defrost, bi-level, high and low, and always hot. So upon inspection I noticed the smell seemed to be coming from the blower motor(under the glove box). The exterior of the motor was extremely hot to touch, painful even. When I turn on any of the heater settings, I can see the ....well I don't know what its called, but it seems vacuum controled, and is to the left of the blower motor. Anyway that part "opens" or "expands" like it always does but the blower does not kick on. I disconnected the cable to the motor and finished my drive. I do still get hot air in the right places when I select any of the settings, but only at driving speeds.

So.. is my blower motor toast? Is it normal for it to be painful to touch? Has anyone ever had their blower go bad, accompanied by a burning smell, almost sweet like coolant.
