1. Find the HVAC Housing: The heater fan is usually housed inside the heating, ventilation, and air conditioning (HVAC) housing. Look under the dashboard, typically on the passenger side, for a large plastic housing with vents. This is the HVAC housing.
2. Remove Access Panels: Some vehicles have access panels or covers that provide access to the heater fan. Locate and remove these panels or covers to expose the HVAC housing.
3. Locate the Heater Fan: Once the HVAC housing is exposed, look for the heater fan. It's usually a circular or cylindrical component with a motor attached to it. The fan may have a squirrel cage design with blades.
4. Check Fan Connections: Inspect the heater fan's electrical connections to ensure they're secure. Disconnect any connectors if necessary to remove the fan.
5. Remove the Heater Fan: Depending on the vehicle, the heater fan may be secured by screws, bolts, or plastic clips. Remove these fasteners to detach the heater fan from the HVAC housing.
Note: The exact location and accessibility of the heater fan can vary depending on the make and model of your vehicle. Refer to your vehicle's service manual or consult with a qualified mechanic for specific guidance on locating and accessing the heater fan under the dashboard in your vehicle.
