hey guys, the other day I installed brand new 5.0 rest door lock actuators in my 91 lx..the install went without a hitch, however after I got everything back together I noticed the drivers side door didn't lock. the rod goes up and down just fine but the door doesn't actually lock. I pulled to door panel back off right away and it seemed like everything was working like it should..nothing was seized up and the mechanism looked just fine..both doors locked perfect before the actuators seized up the first time...what would have changed in door that would not allow the actuator to do its job? did I get a faulty actuator? help.
