Motor blower resistor location on a 2001 Mercury Grand Marquis?

The blower motor resistor on a 2001 Mercury Grand Marquis is typically located behind the glove box. You'll likely need to remove the glove box to access it. It's often a small, rectangular, black component with several wires attached. However, it's not always in the same exact spot, and some variations may exist. A repair manual specific to your vehicle year and model would provide the most accurate location.
