Removal Procedure

The blower motor and fan are located in the lower right corner of the HVAC module. Service this component as an assembly only.

For blower motor electrical diagnosis, refer to Blower Motor Inoperative at Any Speed .

    Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

  1. Disconnect the negative battery cable.
  2. Remove the right sound insulator.
  3. Disconnect the electrical connections at the blower motor.
  4. Remove the blower motor retaining screws.
  5. Remove the blower motor and fan assembly.

Installation Procedure

  1. Install the blower motor and fan assembly.
  2. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  3. Install the retaining screws.
  4. Tighten
    Tighten the screws to 5 N·m (45 lb in).

  5. Connect the electrical connections.
