Parts
- HVAC blower motor assembly × 1 — Use OEM specification
Preparation
- Park vehicle on level surface and engage parking brake
- Turn ignition off and remove key
- Disconnect negative battery cable and wait 2 minutes
- Open passenger door fully for easier access
- Empty glove box of all contents
Procedure
- 1Remove glove boxOpen the glove box fully. Locate the two damper arms on each side of the glove box. Squeeze the sides of the glove box inward to release the stops from the dashboard. Continue squeezing and pull the glove box down and out to remove it completely from the dashboard opening.
- 2Disconnect cabin air filter coverWith the glove box removed, locate the cabin air filter cover on the right side of the HVAC housing. Press the release tabs on both sides of the cover and pull it down to remove. Set aside the cabin air filter if present.
- 3Access blower motor housingLook into the opening behind where the glove box was mounted. The blower motor is located in the lower right area of the HVAC housing. You should see a large circular housing with an electrical connector attached.
- 4Disconnect blower motor electrical connectorLocate the electrical connector on the blower motor. Press the locking tab and pull the connector straight off the blower motor. Move the wiring harness aside to provide clearance for motor removal.
- 5Remove blower motor mounting screwsUsing a 7mm socket or nut driver, remove the three screws securing the blower motor to the HVAC housing. The screws are located around the perimeter of the blower motor flange. Support the blower motor with one hand as you remove the final screw to prevent it from falling.Torque specBlower Motor Screws4 Nm (3 lb-ft)
- 6Remove blower motor assemblyCarefully rotate and pull the blower motor assembly downward and out of the HVAC housing. The motor and fan wheel assembly will come out as one unit. Be careful not to damage the fan blades during removal. Inspect the mounting surface and seal for debris or damage.
- 7Install new blower motorPosition the new blower motor assembly into the HVAC housing opening, ensuring the mounting holes align properly. Rotate the motor as needed to fit the fan wheel into the housing without interference. Verify the seal is properly seated against the housing.
- 8Install blower motor mounting screwsInstall the three mounting screws by hand first to ensure proper thread engagement. Using a torque wrench and 7mm socket, tighten the screws in a star pattern to 4.0 Nm (3.0 lb-ft). This ensures even sealing and prevents distortion of the housing.Torque specBlower Motor Screws4 Nm (3 lb-ft)
- 9Reconnect electrical connectorReconnect the electrical connector to the blower motor, ensuring it clicks into place securely. Gently tug on the connector to verify it is fully locked.
- 10Reinstall cabin air filter and coverIf equipped, reinstall the cabin air filter with the airflow direction arrow pointing toward the blower motor. Reinstall the cabin air filter cover by aligning the tabs and pressing until it clicks into place.
- 11Reinstall glove boxPosition the glove box into the dashboard opening. Squeeze the sides inward and guide it into place. Release the sides to allow the stops to engage with the dashboard. Verify the glove box opens and closes smoothly and that the dampers function properly.
- 12Reconnect battery and testReconnect the negative battery cable. Start the vehicle and turn the HVAC system on. Test all blower motor speeds (1 through 10 on the climate control) to verify proper operation. Listen for any unusual noises and confirm adequate airflow at each speed setting.
Reassembly
- Torque all fasteners to specifications using a torque wrench
- Ensure all electrical connections are fully seated and locked
- Verify glove box operates smoothly and dampers function correctly
Verification
- Start vehicle and test blower motor at all speed settings
- Verify airflow is strong and consistent with no unusual noises
- Check for air leaks around the blower motor housing
- Confirm climate control responds properly to temperature and fan speed changes
- Verify no warning lights are present on the instrument cluster
