: Door can't be locked/unlocked

Good day dears,

My 2009 CTS rare left door is not locking/unlocking automatically. I have to do it manually by pulling up or pushing down the knob.

While locking/unlocking doors, the knob move but not going up or down.

Can it have a simple solution without going to a dealer?

Take the door card off and inspect. Typically it's a simple motor with a plastic arm that's attached to the locking mechanism to operate. The arm may have broken or simply come off as these days they just snap-on with pressure clips.
