Hi Everyone, I hope I am posting this in th right place.

I have a strange problem with my 2005 Loaded Silverado LT 4x4. It has a  Matrix 50.5 alarm remote/start .
 
I am getting this strange "whine" or "motor noise" when I use the door locks, only when the truck is running or when the courtesy power is still on. Otherwise no whine.

The whine is a motor noise and is drivers door only. I hit the button and the door lock "click" then there is this short motor whine afterward. Both when locking and ulocking. I cannot figure out what would be causing this. Any ideas?

Thanks in advance for any help!!

Aftermarket or OEM Radio?

OEM radio but the sound is not coming out of the speakers. It is toward the rear of the door and definitely a motor or servo of some sort.

Thanks!
