door locks sluggish to cycle. if you cycle the locks 2 or 3 times they will not operate at all. Seems to be lacking power, like several strands of wire are broken reducing the current that goes to the locks.

Power door locks have quit working and I am getting a 2AMP draw off the battery which drains it by morning. Could the door lock actuators be doing this?

Power door locks work intermittently. Have to manually lock them. Not fixed yet. Not sure if it is the actuators or a bad ground. Noticed that if I play radio for a minute or so after parking and turning off motor, the locks have more "power" and will work correctly.
