I think I am getting closer to the problem...
I removed the driver's door panel and heard a loud hissing sound coming from the actuator. I believe there is something loose or or worn on that one, possibly the reason why its causing my door locks not to function correctly.
Anyways.. i put in my skinny hands in to the door and found electric wires as well as the vacuum line connected to the actuator. I would like to do a further examination of the actuator.. but have no idea of how to remove this particular one. The actuators of the rear doors were an easy pull.. but this front driver's door seems to work in a different way. Anyone willing to help me figure out how to remove the acutator off the door once the 2 brass screws are taken off?
