Steps
Open the lower dash access
Switch off the ignition and move the passenger seat back. Release the center-console floor panel fastener and pull the panel aside to expose the resistor.
Inspect and remove the resistor
Unplug the resistor connector and inspect its terminals for melting, discoloration, or loose fit. Remove the retaining screws and withdraw the resistor from the HVAC housing.
Install the new resistor
If the connector is damaged, repair it before installing the new part. Seat the replacement resistor in the same orientation, secure its fasteners, and reconnect the plug firmly.
Reassemble and test
Refit the floor panel and its fastener. Turn on the blower and test each speed; stop if the connector heats up or the fan operation remains faulty.
Check your vehicle’s repair manual for exact specifications and fit.
