Removal Procedure

    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 rear engine sight shield.
  3. Disconnect the positive booster cable from the multi-use relay center.
  4. Move the underhood fuse block out of the way.
  5. Disconnect the electrical connectors from the blower control module.
  6. Remove the blower control module from the blower module.

Installation Procedure

  1. Install the blower control module to the blower module.
  2. Connect the electrical connectors to the blower control module.
  3. Move the underhood fuse block to the original position before removal.
  4. Connect the positive booster cable to the multi-use relay center.
  5. Install the rear engine sight shield.
  6. 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.

  7. Connect the negative battery cable.

    Tighten the negative battery cable to 15 N·m (11 lb ft).
