  2. NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.

  3. I1 CHECK THE HVAC (HEATING, VENTILATION AND AIR CONDITIONING) CONTROL MODULE FOR FLASH CODES

    NOTE: Diagnostic flash codes are 4 digit codes communicated via a blinking LED located near the connectors on the HVAC control module.

    • Ignition OFF. Wait 10 seconds.

    • Perform the HVAC control module manual reset: Press and Hold the A/C button while turning the ignition to the ON position. Observe the HVAC control module LED for Flash codes.

    Is Flash Code 3000, 3001, 3002, 3004, 3010, 3011, 3013, 3014, 3020, 3022, 3023, 3024, 3032, 3033 or 3034 present?

    No  DIAGNOSE any other Flash Codes or Symptoms. REFER to HVAC Control Module Diagnostic Flash Codes  or Symptom Charts .

  4. I2 CHECK THE DEFROST VENT DOOR ACTUATOR, FOOTWELL VENT/REGISTER DOOR ACTUATOR, AND TEMPERATURE DOOR ACTUATOR - FLASH CODES 3000, 3001, 3002, 3004, 3010, 3011, 3013, 3014, 3020, 3022, 3023, 3024

    • Inspect the actuator for stripped gears and inspect for a binding or damaged linkage or door.

    Are any of the actuator or door conditions found? 

    Yes  REPAIR as necessary. INSTALL a new defrost vent door actuator, footwell vent/register door actuator or temperature door actuator as necessary. REFER to: Defrost Vent Door Actuator  . REFER to: Footwell Vent/Register Door Actuator  or REFER to: Temperature Door Actuator  . TEST the system for normal operation. If binding or stalling concern is still present, GO to  I3
    No  DIAGNOSE any other Flash Codes or Symptoms. REFER to HVAC Control Module Diagnostic Flash Codes  or Symptom Charts .

  5. I3 PERFORM THE ACTUATOR CYCLE TEST

    NOTE: This test can be used to diagnose the Defrost, Footwell and Temperature actuators and the Climate Control Housing Case binding/mounting problems. If actuator doors are stalling because one of these components has been severely distorted in its current mount configuration, the HVAC System can be put in the Actuator Test Cycle mode. When changing the mounting configuration, such as loosening or shimming a mount fastener location, you must wait a minimum of 27 seconds to see if all Door Out of Range Low codes clear.

    • With the actuators installed in the case and electrically connected, perform the Actuator Cycle test: Press and Hold the Auto button while turning the ignition to the ON position. This will start the actuator cycle test. All actuators will be driven to their Counter Clock Wise (CCW) and Clock Wise (CW) mechanical stops. This cycle, which takes approximately 18 seconds, will be repeated until the ignition is turned off.

    • To correct for door binding/stalling conditions, attempt loosening or shimming a climate control housing mount fastener location. Wait a minimum of 27 seconds to see if the binding or stalling Flash Codes clear.

    Is Flash Code 3004, 3010, 3011, 3013, 3014, 3020, 3022, 3023 or 3024 present? 

    Yes  REPAIR as necessary. INSTALL a new door actuator as necessary. REFER to: Defrost Vent Door Actuator  . REFER to: Footwell Vent/Register Door Actuator  or REFER to: Temperature Door Actuator  .
    No  DIAGNOSE any other Flash Codes or Symptoms. REFER to HVAC Control Module Diagnostic Flash Codes  or Symptom Charts .
