Welp, I lubed it up, but it's not the actuator. New one does the same thing. I was hoping that's all it was and I wouldn't have to troubleshoot. Sometimes it gets the signal to lock and sometimes it doesn't. The switch is sending out the signal, but only the passenger side receives it every time. I guess it has to be in the wiring somewhere, but where?
edit: put the old one back in, messed with it a little and now it works all the time. I guess it might be the BCM, then
