Power Lock Doors Constantly Unlocking

More about locking and unlocking.

Power lock doors constantly unlocking.

I would start by checking for any codes in the computer relating to the power loss and check all of the sensor readings. That should turn up the problem with the power loss. I would treat these as separate issues though. Oh some cars that have electric locking systems have a sensor in the driver side door lock so when you push the lock down on the driver door it makes all the doors lock so if this sensor is malfunctioning it can cause the doors to lock and unlock unexpectedly i ve had this happen before what you can do and this can be done at home though it is easier to have a dealer do it i d do it myself what you can do is take the door apart and either remover the sensor from the lock.

Posting this for a friend who has a 2008 cobalt trying to get some help for him. The remote should also be checked for stuck buttons. If there is a conflict in one of the door locks that tells the module it is not closed or not locked the module will cycle the locks. His power door locks are locking unlocking all by themselves with or without the ignition running.

If this is occurring with the locks as well as a power loss then you may have a bad ignition switch. The doors will relock automatically if you do not open a door within 45 seconds of unlocking the doors with the remote control. The door locks and the alarm will return to their previous state. 1 disconnect the drivers door lock unlock switch from the connector.

It s to the point that he cannot drive the car and i m hoping i can help him with a fix. First try replacing the remote battery to be sure it is not causing the issue. To isolate the cause. You have a intermittent condition.

Drive the vehicle and see if your random lock unlock condition has stopped. The body control module controls the locking function. If it has replace the switch.
