Exactly! 20 years, or 300,000 more miles! Thanks manIf you locks are sticking when you lock/unlock, then yes it is probably your door lock actuator. They have little motors in them that wear out over time. Aisin makes the OEM actuators. This is the best quality for the best price in my opinion. If you search the forum, some have been successful in opening up the clam shells in these actuators and replacing the little motors for under $20 bucks. If you have the time and patience you may want to go this route. I got mine for $118 on Rock Auto. I will replace and hopefully not have to worry about it for another 20 years!
