1999 Pontiac Transport/Montana Sliding door locks

your probably looking at replacing the door lock actuators , listen closely to see if you can hear them making noise when you hit the button , if they make noise and dont move the actuators are the culprat

Thanks Jim.

I did as you said to do. There is no sound at all coming from the door when I press the lock button.

The one door decided to start working on its own. :)

if you have a test light and some help , you can pull the panels and have someone hold the button while you check for power on both sides , in and out, tel you the truth at the dealer we used to just bang on the actuator and they would work sometimes , then we would replace them , lmk
