Steps
Remove the glove box
Empty the glove box, press its sides inward to clear the stops, then lower it and release it from the bottom hinges.
Disconnect and remove the blower motor
Unplug both motor connectors and remove the blower cover. Remove the motor mounting screws, including the ground eyelet fastener, disconnect the cooling hose, and lower the motor out.
Transfer the fan and cooling tube
If the replacement is a bare motor, remove the fan wheel and cooling tube from the old unit. Align the fan splines carefully and seat it on the new motor without cracking the plastic.
Install the replacement motor
Place the motor and fan assembly into the HVAC case and reconnect the cooling hose. Reinstall the screws, making sure the ground terminal returns to its original location.
Reconnect and test the system
Reinstall the blower cover and reconnect both plugs. Refit the glove box, then test the fan on each speed and listen for rubbing or vibration.
Check your vehicle’s repair manual for exact specifications and fit.
