Chevy Impala Blend Door Actuator Reset – A Helpful Guide With 5 Steps

When does your car require a Chevy Impala blend door actuator reset?

If the driver or passenger heat blend door actuator motor doesn’t function well, the airflow in the car will become too hot or cold.

After a Chevy blend door actuator replacement, such a situation also happens. In that case, resetting the air recirculation actuator is essential to keep everything running well.

In this post, I’ll explain the actuator and instruct you to reset it for proper operation. Let’s get going!

Briefly On The Chevy Impala Blend Door Actuator

chevy impala blend door actuator reset

The climate control module has a crucial part – Chevy Impala blend door actuator. This air conditioning control can increase and decrease the temperature in the car.

When adjusting the temperature or airflow, the switch will transfer signals to the air door actuator.

The temperature valve actuator will move the blend door to the proper position to control the interior temperature and ventilation.

The air temperature actuators are on the right and the left. Along with the blend door are also the intake and mode door actuators.

The intake door determines the amount of air entering the engine. It will work when you run the blower.

The mode actuator controls where the airflow comes from. By using the mode switch, the driver can override the automatic setting.

How To Conduct A Chevy Impala Blend Door Actuator Reset

How do I reset my GM blend door actuator? To reset the actuator, you need to: 

  1. Take the actuator out and set the highest heat.
  2. Turn the shaft of the blend door until the vents produce the maximum heat.
  3. Place the actuator in position again.
  4. Switch on the AC system and check if the actuators operate properly.
  5. Put all the components back together.

For the details, you should first determine if the blend door reset is necessary for your car. Some models allow you to do it easily with an electrical diagnostic tool.

If you need a manual procedure, follow the instruction below:

Step 1: Access The Actuator Assembly Based On Type of Vehicle

You can find the air temperature actuator at numerous locations.

Depending on the type of vehicle, there may be a passenger-side blend actuator and a driver-side temperature blend actuator.

The Chevy Impala has two heater head control units, one on either side of the radio beneath the dashboard. There are two electrical connectors behind the actuators.

  1. Take the glove box off to access the bad actuator.
  2. Remove two screws on the top of the glove box.
  3. Pull the glove box down and remove its hinges. Be careful while doing this task Because of the fastened wire connections back of the radio setup or the glove box.

Step 2: Remove The Defective Actuator From Its Position

  1. Remove the driver-side temperature blend door actuator near the heater box with a screwdriver, and then disconnect the wiring clips.
  2. Take the actuator off the shaft.
  3. Ensure that the shaft and actuator are able to be moved.
  4. If the shaft doesn’t move, you need to diagnose it once again and grease the blend door.

Step 3: Switch On Your Vehicle & AC On

  1. Start the car’s engine to warm the interior. Make sure that you engage the emergency brake before starting the engine.
  2. Switching the knob to turn on the HVAC system.
  3. Set the highest heat setting.
  4. Reset the thermal sensor by holding down the AC and Recirc buttons.

Step 4: Impala Blend Door Actuator Calibration

Use the scan tool to clear away every engine diagnostic trouble code and turn the ignition switch off to activate the driver-side heat door actuator.

If you don’t have a scan tool to do the actuator retaliation, follow the blend door calibration procedure below to perform the calibration update:

  1. Disconnect the negative battery terminal.
  2. Turn the engine off while turning the ignition on
  3. Wait for five minutes.
  4. Pull the ignition key out to stop it.
  5. Reconnect the negative terminals for the battery charging.
  6. Put the ignition key in position, then turn it on.
  7. Wait five minutes before adjusting the air conditioning controls.
  8. Start the car and check if the door opens as you move.

Step 5: Reassemble

  1. Set the maximum heat.
  2. Turn the shaft of the blend door until the vents produce the maximum heat.
  3. Reassemble the actuator.
  4. Experiment with the temperature control settings to guarantee that warm and cold air is arriving.
  5. Check for security and give the HVAC system another try. You should utilize a repair handbook or ask a professional mechanic if anything seems wrong.

When Would You Need A Chevy Impala Blend Door Actuator Reset

Wrong airflow results, inconsistent airflow, and a strange noise behind the dash panel are typical signs of a faulty blend door unit.

Wrong Airflow Results

When the AC blows cold or the constant high heat on climate control, people usually check to see if the AC stops blowing at high speeds or not.

But, you may not know it also is one of the most typical symptoms of a bad blend door operation.

No matter how high you set the temperature, if the HVAC actuator fails, it will often default to the lowest setting. Sometimes, you try to blow cool air, but it still comes out hot.

Inconsistent Air Flow

Inconsistent temperature and airflow are another sign of a bad blend or heat door actuator.

When the blend door swings back and forth, the airflow is disrupted, deviating from the normal flow and discomforting the driver and passengers.

Annoying Clicking Noise In Dash

If you notice some strange clicking sound coming from under the dash, there may be one of the clutch actuator symptoms.

But, it may also be an issue with one of the components of the heater control unit.

Your air floor ducts may be rattling about and loose, which might cause a dreadful clicking noise.

The sound disappears when you switch off your HVAC, which will help you determine the issue.

If it does, the issue is probably with the blower motor. If the strange noises continue while you are driving, the loose parts in the dash may bounce about.
