Blend Door Actuator Calibration

Hello there. I’m going to be replacing an actuator in a 2010 Chevy Impala LT because of that dreadful clicking noise that seems to happen with these vehicles. That’s all fine, but then I heard that you have to calibrate the actuators. I have a Bluedriver scan tool, but I don’t think that would work. I hear other things such as pulling a fuse or disconnecting the negative battery cable. I’m not sure what the proper way is. If anyone can help, I’d appreciate it.


The following is the procedure from way back in 2004. There is a small chance that it will work for you. As stated earlier GM service information says the only way to perform a recalibration is with a compatible scan tool.

The battery power fuse for your 2010 Impala would be the “Display” fuse located in the underhood fuse box.

Actuator Recalibration

Calibration Procedure

Use the following steps to perform the calibration update:

Turn OFF the ignition.
Remove the battery positive voltage circuit fuse of the HVAC Control Module.

Important: The module memory will not clear if the battery positive voltage circuit fuse is installed in less than 60 seconds.

Wait 60 seconds.
Install the fuse.
Wait 60 seconds before moving the HVAC controls.
