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
