Blend door actuator?

This sounds like you have a blend door actuator that has broken some gears which is common, they are plastic. Here is a guide that will give you an idea on what you are in for when doing the job. Remove the glove box door so you can get in behind it so you can feel which one is making the noise. I believe there are three or four of them.

Here is what it will be like on your car. (below)

Please let us know what happens.

Hello,

I have included the information that you requested in the diagrams down below. I have included the instructions from the vehicle manufacturer for your vehicle's blend door actuator removal and installation. Please go through this guide and report back with how everything turns out.

Thanks,

There are multiple blend doors depending on which system you have. They are all located on the drivers side of the HVAC unit. The diagram shows the mode door and both blend door actuators. If you do not have the dual zone system up front you will be missing one of the actuators.
Once you install a new one you need to do a calibration.

The A/C-heater control module must be recalibrated each time an actuator motor or the A/C-heater control is replaced. If the vehicle is so equipped, the calibration procedure also includes rear HVAC positions for each actuator motor.

1 Turn the ignition switch to the "on" position.

2 If equipped with the manual temperature control (MTC) system, press and hold the rear wipe/wash and re-circulation buttons for at least five seconds. If equipped with the automatic temperature control (ATC) system, simultaneously press and hold the power and re-circulation buttons on the A/Cheater control for at least five seconds. The MTC A/C-heater control rear wipe/wash button light emitting diode (LED) and re-circulation button LED, or the ATC A/C-heater control Delay and re-circulation graphics will begin to flash when the calibration procedure has begun.

3 The calibration procedure should take less than two minutes to complete for the manual A/C-heater control, and less than twenty seconds for the ATC A/C-heater control. When the LED's or graphics stop flashing, the calibration procedure is complete.

4 If the LED's or graphics continue to flash beyond the two minute (manual) or twenty second (ATC) calibration time, it indicates that the A/C heater control has detected a failure and a diagnostic trouble code (DTC) has been set. The LEDs or graphics will continue to flash even after the ignition switch is cycled off and on, until a successful calibration is completed or until the vehicle has been driven about thirteen kilometers (eight miles).

Hey JANDREWS319,

This sounds like a blend door actuator problem. Here is some diagrams to show you which one to replace.

Here is a guide to help give you an idea on what you are in for when replacing one of them

Try to see if you can calibrate the system first. Here is the calibration procedure.

The heater-A/C control module must be recalibrated each time an actuator motor or the control module is replaced. If the vehicle is so equipped, the calibration procedure also includes rear HVAC positions for each actuator motor.

Turn the ignition switch to the ON position.
Simultaneously depress and hold the Power and Recirculation buttons on the heater-A/C control for at least five seconds. The manual heater-A/C control power Light Emitting Diode (LED) and Recirculation LED, or the Automatic Temperature Control (ATC) heater-A/C control Delay and Recirculation graphics will begin to flash when the calibration procedure has begun.

The calibration procedure should take less than two minutes to complete for the manual heater-A/C control, and less than twenty seconds for the ATC heater-A/C control. When the LEDs or graphics stop flashing, the calibration procedure is complete.

If the LEDs or graphics continue to flash beyond the normal three minute (manual) or twenty second (ATC) calibration time, it indicates that the heater-A/C control has detected a failure and a Diagnostic Trouble Code (DTC) has been set. Use a DRB III scan tool to perform further diagnosis. Refer to the appropriate diagnostic information. The LEDs or graphics will continue to flash even after the ignition switch is cycled OFF and ON, until a successful calibration is completed or until the vehicle has been driven about 13 kilometers (8 miles).

If that does not work you would need to take it in to have it scanned for trouble codes and diagnosed from there.

Hope the calibration works out for you.

Please let us know what you find so it will help others.

Best, Ken

Hello,

This job can be done which will take some doing and you might need to loosen the dash and remove some obstacles to get to the mode door actuator. Here is a guide to walk you through the steps and diagrams below to show you how on your car.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

What your going to have to do is remove actuator to see if the part that slides into the actuator is broken?If not make sure the door moves freely by hand if so I would say the actuator is bad.

This is the book procedure.

Turn the ignition switch to the "on" position.

If equipped with the manual temperature control (MTC) system, press and hold the rear wipe/wash and re-circulation buttons for at least five seconds.

If equipped with the automatic temperature control (ATC) system, simultaneously press and hold the power and re-circulation buttons on the A/C-heater control for at least five seconds.

The MTC A/C-heater control rear wipe/wash light emitting diode (LED) and re-circulation LED, or the ATC A/C-heater control delay and re-circulation graphics will begin to flash when the calibration procedure has begun.

The calibration procedure should take less than two minutes to complete for the manual A/C-heater control, and less than twenty seconds for the ATC A/C-heater control. When the LED's or graphics stop flashing, the calibration procedure is complete.

If the LED's or graphics continue to flash beyond the two minute (manual) or twenty second (ATC) calibration time, it indicates that the A/C - heater control has detected a failure and a diagnostic trouble code (DTC) has been set.

Refer to body diagnostic procedures to perform further diagnosis. The LED's or graphics will continue to flash even after the ignition switch is cycled off and on, until a successful calibration is completed or until the vehicle has been driven about 13 kilometers (8 miles).
