I am not familiar enough with these J-body's yet, but did you check your fuses yet? there are fuses under the hood and on the driver's side dash.
It sounds like a short somewhere if the blower motor comes on and off by throttle input though.
New guy here, but that certainly sounds like an electric issue.
If you are not putting out enough amps the fan power would fluctuate.
Hows the Alternator, Battery and serp belt?
had that problem before, turns out it was a bad ground at the battery!
