96 EX V6 with 160k miles. For awhile now when we lock the car all the door locks kept trying to lock for multiple cycles for a few seconds. The problem is now worse - they keep locking for over a minute now - all the doors. This has to be really hard on some component(s) - as well as drawing down the battery and just plain annoying. I'm reading this is probably a door lock actuator problem but it can't be all 4 actuators going bad. Will 1 bad actuator - or even something else cause this problem? Thanks.
