  • Disconnect the battery negative cable.
  • Remove the VCM. Refer to VCM Replacement/Programming in Engine Controls - 4.3L.
  • Remove the coolant reservoir. Refer to Coolant Recovery Reservoir Replacement in Engine Cooling.
  • Remove the rear coolant recovery reservoir mounting stud.
  • Disconnect the electrical connector from the blower motor.
  • Remove the blower motor access cover retaining screws.

    Important: Cut through the cover as straight as possible because the access cover must be replaced. Part of this repair is visible to the customer. In order to prevent damage to the component, do not cut any deeper than is necessary in order to remove the access cover.

  • Cut through the cover on the cut line (1) using a razor blade or a sharp utility knife.
