On the dash, the control knob for the fan is in the off position but runs continuously.
I don't have to turn the fan on, it begins when I start my 2003 Pontiac Montana. I can't
control the amount of air flow either. It's in the off position and when I move it from 1 to 5
settings, the air flow doesn't change. Could the switch be bad or a fuse or resistor? My
A/C works, heat works and I can change where the air comes out, just can't turn it off.
Any help would be appreciated.
