GMC Suburban 2500 Power Door Lock Actuators May Fail
The power door lock actuators may become slow to operate or stop working completely and require replacement.
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. - Visitor

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. - rbarthis
