Message: <blockquote data-quote="huskar3399" data-source="post: 643119" data-attributes="member: 25472">today i got chance to play with door lock actuator on driver side. the reason was my door suddenly could not be lock/unlock from both inside and outside. so i made some searching on the internet, majority say faulty actuator is the culprit. i did not have new actuator in hand but just for fun and to see what's happening on the inside of the actuator i took it out. it was not easy especially for a first timer like me. after the actuator was out i sprayed whatever mechanical connections that i could see using silicone spray with straw. i read it is not advisable to spray using wd40 because it will strip away existing lubricant there thus making the actuator more difficult to play. i did not put so much hope the actuator is going to work like normal again so i just reinstalled. but somehow it worked just fine to lock and unlock the door. i don't understand how but i believe it is most likely because of the silicone lube that i sprayed. hopefully it will last long. touch wood. lol.i used these 2 links as guidance.<a href="http://www.bimmerfest.com/forums/showthread.php?t=648959" target="_blank">http://www.bimmerfest.com/forums/showthread.php?t=648959</a><a href="http://tis.spaghetticoder.org/s/view.pl?1/01/23/46" target="_blank">http://tis.spaghetticoder.org/s/view.pl?1/01/23/46</a>the actuator is out<img src="https://lh4.googleusercontent.com/-HNAk0L9T0D8/UKeROV_7xxI/AAAAAAAAAqk/f0RgE_BenPo/s640/image%2520%25281%2529.jpeg" alt="" class="fr-fic fr-dii fr-draggable " style="" />springs where i sprayed the silicone<img src="https://lh4.googleusercontent.com/-VHhQzd7WiOM/UKeROZw7PRI/AAAAAAAAAqs/BT7KUDDlpkU/s640/image.jpeg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></blockquote>
