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.

I'd disconnect the neg. batt. cable while replacing the bda. Prior installing the new 1, position the shaft to match the old 1. You can do this with 2 jumper wires and a battery source or simply plug the new 1 in to align it unless it's the drivers side temp control, lol. No formal reboot/calibration needed.
Bluedriver doesn't address it
try this- it worked for my 2008 9C3
DORMAN BLEND DOOR 604-108 $12.99
Recalibration instructions:
1. Disconnect negative battery cable
2. Turn ignition on- engine off
3. Wait 5 minutes
4. Turn off ignition (remove key)
5. Reconnect battery cable
6. Insert key and turn ignition on- engine off
7. Wait 5 minutes- do not adjust HVAC controls
8. Done-start car and observe if door operates with circulate/recirc

I realize its an older thread. The clicking noise indicates the gear inside the actuator is broken. It's very common and the fix is to replace the actuator.
