Repair\/replace the connector or terminal.<\/p>\n

After repair procedure, go to the next step.<\/p>\n<\/td>\n<\/tr>\n

\n

5<\/p>\n<\/td>\n

\n INSPECT CLIMATE CONTROL UNIT POWER SUPPLY CIRCUIT FOR SHORT TO GROUND<\/b><\/p>\n
    \n
  • \n

    Inspect for continuity between climate control unit terminal L and body ground.<\/p>\n<\/li>\n

  • \n

    Is there continuity?<\/p>\n<\/li>\n<\/ul>\n<\/td>\n

\n

Yes<\/p>\n<\/td>\n

\n

Refer to the wiring diagram and verify whether or not there is a common connector between climate control unit terminal 1B and battery positive terminal.<\/p>\n

    \n If there is a common connector:<\/b><\/p>\n
  • \n

    Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.<\/p>\n<\/li>\n

  • \n

    Repair or replace the malfunctioning part.<\/p>\n<\/li>\n<\/ul>\n

      \n If there is no common connector:<\/b><\/p>\n

\n

No<\/p>\n<\/td>\n

\n

Refer to the wiring diagram and verify whether or not there is a common connector between climate control unit terminal 1B and battery positive terminal.<\/p>\n

    \n If there is a common connector:<\/b><\/p>\n
  • \n

    Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.<\/p>\n<\/li>\n

  • \n

    Repair or replace the malfunctioning part.<\/p>\n<\/li>\n<\/ul>\n

      \n If there is no common connector:<\/b><\/p>\n
    • \n

      Repair or replace the wiring harness which has an open circuit.<\/p>\n<\/li>\n<\/ul>\n
