Using a vacuum pump is there a way to test the doors without the engine running. I know with a pump you can but I guess the question is how. Every possible componet is brand new and the doors move easily by hand. Hooking vaccum to either the red or green line should open and close the doors correct? I got one side to open (doing one side at a time) but I couldn't get it to close and the doors were tight so I couldn't even do it by hand. That was last night. By this morning I could close it as there wasn't that much pressure. It seems vacuum is holding it tight in one place , open or shut. Besides my issues I guess the main question is how do I test them to make sure they will work before I start the car. I would be happy just being able to test each light individually using the green and red line from each actuator but I don't know if using vacuum on one line if the other should be open or plugged or what. I can't really get them to work and I don't suspect I have bad actuators at this point because they feel ok when I do the lights manually and such. I am going to try and borrow a book but I wanted to do this tonight or tomorrow which doesn't leave time to try and borrow a book or go buy one which I am tapped anyway, the car is killing me and this is bugging me the most. If its hard to explain then I would accept a fax of some kind of a troubleshooting guide if there is one. Can someone explain how to hook up and use the vacuum pump to test the headlights? Sorry for the long post!
