  1. Check Blend Door Actuator System

    Start engine and run to operating temperature. Turn on MAX A/C mode and temperature knob to COOL. Check for cool air. Turn temperature knob to WARM and check for warm air. Repeat several times. If temperature changes, system is okay. If temperature does not change, check fuse No. 17. If fuse is not okay, replace. If fuse immediately blows, check for short circuit from Light Blue/Pink wire to ground. See Fig 1.

  2. Check Electric Blend Door Actuator Supply Voltage

    Disconnect Blue 6-way connector on evaporator case. Check for battery voltage (B+) between Light Blue/Pink terminal and Black terminal. See Fig 1. If voltage is not present, check wiring to connector. If battery voltage is present, proceed to step 3.
    NOTE: If replacement actuator is available, jumper harness to connector and operate system. Check for actuator function.
