Removal Procedure

    Object Number: 295302 Size: SH
  1. Remove the front floor kick-up panel. Refer to Front Floor Kick-Up Panel Replacement in Interior Trim.
  2. Remove the cover from the I/P electrical center.
  3. Remove the BLO MOT MaxiFuse® #49 from the I/P electrical center.
  4. Remove the RH lower I/P insulator panel. Refer to Instrument Panel Insulator Panel Replacement - Right Side in Instrument Panel, Gages and Console.
  5. Disconnect the wiring harness electrical connector from the blower motor resistor.

    6. Object Number: 295327 Size: SH
  6. Disconnect the blower motor resistor electrical connector from the blower motor.

    7. Object Number: 295304 Size: SH
  7. Loosen the blower motor resistor forward retaining screws (nearest the dash mat) approximately 5 mm (0.197 in).

    8. The resistor is slotted at the forward retaining locations.

  8. Remove the resistor rear retaining screw.
  9. Tilt down the rear of the resistor; use care to not damage the portion of the resistor which fits up into the HVAC module.
  10. Remove the blower motor resistor from the vehicle.
  11. Inspect the condition of the blower motor resistor seal. Replace if necessary.

Installation Procedure

    Object Number: 295304 Size: SH
  1. Position the blower motor resistor forward retaining slots onto the forward retaining screws and the upper portion of the resistor into the HVAC module.
  2. Align and seat the resistor to the HVAC module.
  3. Install the resistor rear retaining screw and drive until just secure.

    4. 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.

  4. Tighten all the resistor retaining screws.

    5. Tighten
    Tighten the screws to 1.6 N·m (14 lb in).
