Steps
Remove the glove box
Empty the glove box, release its hinge pins and stops, then disconnect the tether and set the box aside.
Remove the lower dash trim
Remove the trim screws and release the rocker-panel and dash clips. Disconnect the trunk switch and any lamp wiring before moving the trim panel away.
Remove the blower motor
Unplug the blower connectors, release the motor cover tabs, and remove its screws. Free the harness from the motor and lower the assembly out of the HVAC housing.
Transfer the resistor and protective parts
Move the flex hose, wiring clip, resistor, and rubber cover from the old motor to the replacement as required. Secure the resistor and confirm the parts are seated.
Install the replacement motor
Lock the motor into the HVAC case, reconnect its harness and other electrical plugs, and reinstall the mounting screws without pinching wires.
Reinstall trim and test fan speeds
Reconnect the switch and lamp, press the dash trim clips into place, and reinstall the screws and glove box. Test the blower at each speed and listen for rubbing.
