How do you stop doors locks from locking and unlocking by them self when driving door locks keep trying to lock or unlock?

Answer 1

Find the problem and fix it.

If equipped with RKE, verify that buttons of RKE transmitter are not accidentally pressed by other keys.

If you have aftermarket electronics such as a remote start or add-on alarm, check for any problems in the added wiring and in control module for this item.

If this is a conversion van or RV type vehicle, modifications have been made before the vehicle was resold as new. In many cases these modifications involve wiring splices or addition of interior/exterior trim using fasteners which can occasionally damage existing wiring. Look for any related problems.

If this vehicle has had any water leaks (such as damaged weatherstrip or window left open during rain) check for any damage to door lock switches including internal corrosion near water leak.

If this is a GM vehicle, check for possible faulty BCM by banging BCM with hammer while undesired door lock operation is occurring. If banging with hammer affects unwanted door lock operation, replace BCM.
