The front passenger electric door lock just stopped working. I can manually open or close the switch, but when I lock (or unlock) the car with the remote, this one switch does not lock (or unlock). I see it try to move (either open or close), but it doesn't quite lock or unlock electronically. Since all of the other doors and rear hatch work fine, perhaps there is a way to lubricate this mechanism? I'd rather try something myself than bring it to a dealer and pay more than I need to.
