actuator or vac. line?
 

I have a large vac. leak which caused the car to not shut off. I've isolated it to the LR (drivers rear) door. Have the actuator removed and it doesn't hold vacuum, but operates. Testing the lines to the door also leak. So, what gives? I'd like to know more about the actuator, if anyone could share their experience and/or knowledge.

Thanks

Those rubber connectors under the carpet do tend to crack and leak also.

IIRC, the new style black door lock actuators are not rebuildable, while the older blue ones are. Only problem is trying to find replacement diapragms for the blue ones. Either way, the actuators should hold vacuum.
