How to Replace Blower Motor Resistor 95-11 Ford Ranger
Difficulty: Beginner · About 60 min · Ford Ranger
Replace the blower motor resistor on a 1995–2011 Ford Ranger when some fan speeds stop working. Test all settings before and after; a failing motor or damaged connector can cause similar symptoms.

Steps
Confirm the fan-speed problem
Turn the ignition on and run the blower through each setting. Note which speeds work, then switch the ignition off before disconnecting wiring.
Move the coolant bottle
Remove the bottle's 11mm nuts and 10mm fasteners, then move it aside gently without stretching or kinking its hoses.
Remove and replace the resistor
Unplug the blower wiring and detach the vent tube. Remove the two resistor fasteners, release its connector without forcing the plastic lock, and install the replacement securely.
Test and restore the vehicle
Reconnect the vent and blower, reinstall the coolant bottle, and test every fan speed. If speeds still fail or the connector is heat-damaged, diagnose the circuit before further use.
Check your vehicle’s repair manual for exact specifications and fit.
