WHY DOES MY CAR SMELL LIKE WIRES ARE BURNING?

2003 Mercury Sable • 145,000 miles

I first noticed my the car making a grinding noise when I turned the heat on, the noise stopped but now it smells like burning plastic/wires when I turn it on. There is no problem when the heat is turned off.

This sounds like a failing heater blower motor.
