I've had the dreaded traction control, stabilitrac loss of power etc problems like many others. I've replaced the battery, just replaced the throttle body today. I ran a scan after that and came back with 0 codes. Now while I'm driving, my door locks will lock and unlock like crazy. I cleaned the grounds when i changed the battery, but it's still happening. Could it be the door lock actuator? I'm worried its a loose wire somewhere and i have no idea where to start. Any help would be appreciated. I really have researched this extensively, and trying to fix things as i go, but I'm at my wits end. 2010 Traverse LT with 140,000.
