How do you turn on rear defroster a Ford Tempo?

The Ford Tempo's rear defroster is typically activated by a button. It's usually located on the center console, near other climate controls like the heater, AC, and fan speed. Look for a button with a symbol depicting a rear window with lines radiating from it, sometimes accompanied by the word "DEFROST" or "REAR DEFROST". Pressing this button will turn the defroster on or off.
