You must remove portions of the Instrument Panel assembly in order to gain access to the air distribution ducts as required. Refer to Instrument Panel Carrier Replacement or Instrument Panel Carrier Replacement in Instrument Panel Assembly in Instrument Panel, Gauges and Console.

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 accessory trim plate. Refer to Instrument Panel Accessory Trim Plate Replacement in Instrument Panel, Gauges and Console.

Installation Procedure

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.
