The Heater Only System; The Knobs That Control The Standard Heating Only System - Ford 1996 Mustang Manual

Under normal conditions, the SELECT knob
should be left in any position other than MAX
A/C or OFF when the vehicle is parked. This
allows the vehicle to "breathe" through the
outside air inlet duct.

You can heat the inside of your vehicle, defrost
the windshield, or use the vents by adjusting the
