So I think I have the door lock actuator going in the front passenger side door of my minivan. The high pitch squeal along with the door lock not unlocking or locking anymore. I'm wondering if anyone would have some helpful hints in replacing the actuator. Is it one that is serviced separately or is it part of a larger unit? I noticed that Autozone and Oreillys online do not show an actuator for the front doors, just the sliding and the rear doors. This leads me to believe something is "special" about the front doors I've never had one go in any of my vehicles before so this will be a new project for me. Thanks for your help! I hope everyone has a nice holiday season!
