Where is the blower motor resistor on a 2000 ford expedition 4.6?

The blower motor resistor on a 2000 Ford Expedition with a 4.6L engine is located under the dashboard, on the passenger side, typically near the blower motor itself. To access it, you may need to remove the lower dash panel and possibly the glove compartment. The resistor is often mounted to the HVAC housing and is connected by a wiring harness.
