Question about 1997 Pontiac Grand Prix
The fan on the passenger side of my car stays on full blast even when the car is off. I am forced to pull the fuse everytime I am done driving. Is there any way to fix it or is there a fuse I can leave out all the time that won't disable my headlights?
If the heater blower motor resistor failed then the heater will stay on full blast to keep your window clear, for safety. If the key is turned off and the fan still blows then I suspect you have an ignition switch problem. Main power comes from the key switch to feed the heater system. The plug at the ignition switch could be melted and making contact or an internal switch problem. The switch is located on the steering column under the plastic cover.Unplubbing the switch should help diagnos the problem.
