It is probably a bad motor, or a loose ground going to the motor. And there is the possibility of a bad switch, if it only occurs at one speed.

Why would the heater and defroster work first thing in the morning but not during the day once it has been shut off in a 1995 Bonneville?

heater fan problemI'm haveing the same prblem in my 1997 Bonneville and have been told after paying $80 for the diagnosis by the Pontiac service department that it is the fan motor that needs to be replaced. I believe that there is a sensor of some kind that is attached to the heater fan which has gone bad. I haven't replaced it yet but it cost around $50 to buy the fan so it's an easy fix if what the Pontiac service department said is true. Don't let them do it they will charge you around $250 for the same repair!
