Ok so today I noticed that my passenger door lock had stopped responding. Usually, whenever the driver lock is moved, the passenger lock follows, whether manual or by the door switch or key switch. Now, it won't go up or down unless i do it manually. When i push the button, it twitchs a little, as if it wants to move, but nothing. I think it was going gradually, because sometimes when id press the unlock button on the key, only the driver door would unlock unless i pressed it a couple times. any hlp?
