* Behind the glove box: This is a very frequent location. You might need to remove or partially remove the glove box to access it.
* Below the dashboard on the passenger side: Sometimes it's accessible by reaching under the dash, but often requires partial disassembly.
* Within the HVAC housing: This is less common but possible, requiring more extensive disassembly of the dashboard.
To find it, you'll likely need to:
1. Consult your vehicle's repair manual: This will give you the most accurate location for your specific year and model.
2. Search online for your specific year and model: Many forums and repair sites have pictures and descriptions of the resistor location for specific E-350s. Be sure to specify the year.
3. Use a wiring diagram: Tracing the wires from the blower motor can lead you to the resistor.
Without knowing the exact year and model of your Ford E-350, it's impossible to give a precise location. Remember to disconnect the negative battery terminal before working on electrical components.
