This procedure covers the removal and replacement of the HVAC blower motor assembly located in the passenger footwell area of the 2018-2024 Honda Accord 1.5L Turbo.

Warnings

Tools required

Parts

• Blower motor assembly × 1 — Use OEM specification or quality aftermarket
• Blower motor resistor (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key/fob from vehicle
3. Disconnect negative battery terminal and wait 3 minutes
4. Remove passenger floor mat and any items from passenger footwell area
5. Position work light to illuminate passenger side lower dash area

Procedure

1. 1

   Access the blower motor area
   From the passenger footwell, locate the lower dash panel cover below the glove box. This cover protects the blower motor assembly. You may need to partially recline the passenger seat for better access.
2. 2

   Remove lower dash panel
   Remove the Phillips screws securing the lower dash panel cover (typically 2-3 screws). Carefully pull the panel away from the dash, releasing any plastic clips. Set the panel aside with screws in a safe location.
3. 3

   Disconnect blower motor electrical connector
   Locate the blower motor electrical connector. Press the locking tab and pull the connector straight off the motor. The connector has a positive lock that must be released before removal. Note the orientation for reinstallation.
4. 4

   Remove blower motor resistor (if applicable)
   If the blower motor resistor is blocking access or being replaced, remove the screws securing it to the blower motor housing. Disconnect its electrical connector by pressing the release tab. Set aside if reusing.

5. 5

   Remove blower motor mounting screws
   Locate and remove the three Phillips screws securing the blower motor assembly to the HVAC housing. Support the motor with one hand while removing the final screw to prevent it from dropping.

6. 6

   Extract blower motor assembly
   Carefully rotate and lower the blower motor assembly out of the HVAC housing. The motor and fan cage assembly will come out as one unit. Take care not to damage the fan blades during removal. Inspect the housing for debris or obstructions.
7. 7

   Inspect and clean
   Inspect the HVAC housing opening for leaves, debris, or signs of water intrusion. Clean any debris from the housing. Check the blower motor seal/gasket and replace if damaged. Verify the new blower motor matches the old unit in connector type and mounting configuration.
8. 8

   Install new blower motor
   Position the new blower motor assembly into the HVAC housing, aligning the mounting holes. Ensure any seal or gasket is properly seated. Insert all three mounting screws and hand-tighten before final torquing.

   Torque blower motor screws
   Using a torque wrench, tighten the three blower motor mounting screws to specification in a cross pattern to ensure even seating of the motor against the housing.

    Reinstall blower motor resistor
    If the blower motor resistor was removed, reinstall it to the blower motor housing. Connect its electrical connector until it clicks. Torque the resistor screws to specification.

11. 11

    Reconnect electrical connector
    Reconnect the main blower motor electrical connector, ensuring it clicks fully into place. Verify the locking tab is engaged and the connector is secure.
12. 12

    Reinstall lower dash panel
    Position the lower dash panel cover back into place, engaging any plastic clips first. Install and torque the Phillips screws to specification. Verify the panel is flush and secure.
13. 13

    Reconnect battery and test
    Reconnect the negative battery terminal. Turn the ignition to ON (do not start engine). Test the blower motor at all speed settings (1-4 or Lo-Hi depending on trim). Listen for unusual noises and verify airflow is strong and consistent at each setting.

Reassembly

1. Ensure all electrical connectors are fully seated and locked
2. Verify lower dash panel is secure with no rattles
3. Reinstall passenger floor mat

Verification

• With engine off and ignition ON, test blower motor at all speed settings
• Verify smooth operation with no grinding, squealing, or vibration
• Check that airflow is strong and consistent across all fan speeds
• Confirm no air leaks around the blower motor installation area
• Test in both recirculation and fresh air modes to ensure proper operation
