How to Remove and Replace Toyota Yaris Heater Fan | Parts Factory Australia

Introduction

This tutorial provides a step-by-step guide on how to remove and replace the heater fan blower motor in a Toyota Yaris (2005-2011 model). Whether you're facing issues with your heater fan or just looking to perform maintenance, this guide will help you complete the task with ease using basic tools.

Step 1: Prepare Your Workspace

• Ensure you have a comfortable area to work. If you're on the floor, consider using a soft mat or kneeling pad to protect your knees.
• Move the passenger seat as far back as possible to create more space for working under the dashboard.

Step 2: Gather Required Tools

You will need:

• 8mm socket wrench with a short extension
• Flathead screwdriver (optional for unplugging the connector)
• Ratchet (preferably a quarter-inch)

Step 3: Locate the Heater Fan Blower Motor

• The heater fan blower motor is located under the left side of the passenger footwell.
• Identify the three 8mm bolts securing the blower motor and the electrical connector.

Step 4: Disconnect the Electrical Connector

• If you prefer, you can leave the plug connected, but it’s recommended to unplug it for easier access.
• To unplug, gently pull the clip down and disconnect the plug.

Step 5: Remove the Old Blower Motor

• Using your 8mm socket wrench:
  • Start by loosening the back bolt first, then remove it completely.
  • Next, remove the two front bolts.
• Once all bolts are removed, gently pull the blower motor out. Don’t worry if it falls; it won’t be damaged.

Step 6: Compare the Old and New Motors

• Before installation, compare the old blower motor with the new one to ensure they match.
• The new motor should have similar dimensions and connector fittings.

Step 7: Install the New Blower Motor

• Position the new blower motor in place, ensuring the cone end faces the correct direction.
• Secure the motor by:
  • Starting with one of the bolts to hold it in place.
  • Hand-tightening the other two bolts.

Step 8: Reconnect the Electrical Connector

• Plug the electrical connector back into the new blower motor.

Step 9: Tighten the Bolts

• Use your socket wrench to tighten all three bolts securely.

Step 10: Test the New Blower Motor

• Turn on your vehicle and test the heater fan to ensure it operates correctly.
• Adjust the speed settings to confirm functionality.
