Actuator is clicking

The actuator as I learned to call it, is clicking behind the ac or radio even without the engine running. I just unlocked the door and it started clicking. It will stay like that for a minute or so.

I believe the correct name for the part is BLIN door actuator and depending on the year your Impala and if you have dual zone controls there could be three of these actuators. On my 2012 LTZ they started clicking one after another in pretty quick succession. Good thing is the part is pretty inexpensive. Below is a link to one of many YouTube videos for replacing these actuators.

Pinpointing which one it is may be easy or not so easy depending on which one it is. The easiest one to get to can be unplugged and you can either rule it out or get lucky and that be the bad one. When we had the clicking, just like you mention that continued after the key was out and the car sitting, it stopped as soon as I unplugged the actuator, telling me that was the bad one. Very easy to change that one and the genuine gm part from rock auto is like $24. There are 2 types of actuator in each car though and you have to get the right one for to replace the bad one. The other two you can see from inside the glove and are a bit harder to get to. My understanding is there is a 4th one in some cars that is further into the middle and a bit more difficult to get to.

My 6 year constantly asks why. What adults can learn from 5 and 6 year olds, to listen with your ears and mind open. Hard to learn when you don't listen ......
