Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Is this an Olds Aurora? Does only one of the door locks not work properly?
Do both rear windows operate? Does door ajar indicator on dash illuminate when either rear door is opened?
The door locks and windows operate through modules in each door. Since the windows operate, there is communication to these modules. The problem then is going to be in the door lock actuators in each of the rear doors. The actuator is located at the door latch at the rear edge of the door. Remove the door panel for access.
First manually unlock the doors using the lever inside the car. Open the door then remove panel.
1. Remove the inside door handle bezel. Refer to Door Inside Handle Bezel Replacement
2. Use a thin tool to pry out the retainers (3) around the outside edges of the door trim panel (1).
3. Remove the door trim panel by pulling out at the bottom of the panel and lifting up.
Can you manually move the door lock levers?
