Electric Door Locks

[ROGJOA*]

Whether using the remote or driver's door switch, the door locks/hatch back lock on my '91 RX300 only partially engage. Although one can hear the sound of an attempted locking, none of the doors/hatch back completely lock. This was a simultaneous failure rather than a gradual degradation, i.e., one door at a time.

My guess is there is an electrical circuit failure that resulted in insufficient voltage/current to the locks. Any similar experience out there/solution?

Thanks

Power door locks (also known as electric door locks or central locking) allow the driver or front passenger to simultaneously lock or unlock all the doors of an automobile or truck, by pressing a button or flipping a switch.

Power door locks were introduced on the luxury Scripps-Booth in 1914, but were not common on luxury cars until Packard reintroduced them in 1956. Nearly every car model today offers this feature as at least optional equipment.

Early Electrical Circuits locked and unlocked only the car doors. Many cars today also feature systems which can unlock such things as the luggage compartment or fuel filler cap door. It is also common on modern cars for the locks to activate automatically when the car is put into gear or reaches a certain speed.
