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 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!
