Steps
Disconnect the resistor harness
Switch off the ignition and locate the blower motor resistor on the HVAC case. Release its electrical connector by the locking tab, pulling on the plug body rather than on the wires.
Remove the old resistor
Remove the two Phillips retaining screws and withdraw the resistor from the housing. Check the connector and surrounding plastic for signs of overheating, melting, or corrosion before fitting the replacement.
Install and test the replacement
Insert the new resistor in the same orientation and ensure it sits flush against the HVAC housing. Reinstall both screws, reconnect the wiring plug, then switch on the ignition and test each blower speed setting.
Check your vehicle’s repair manual for exact specifications and fit.
