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!

Your heater core is leaking in it's housing box and blowing moist air through the heater/defroster. Try bardall radiator stop leak. If no help, install new heater core. Chuck.

Begin by training the water from your 1997 Pontiac Bonneville cooling system. Remove the heater core water supply hoses. Remove the heater core retaining bolts. Reverse the process to install the new heater core.
