You have to set everything up based off the relay switch under the hood. If the doors work backwards then the hoses at either end, meaning actuators or dash switch, are not connected properly. Full vacuum should be present at the dash switch, the reservoir and the "Y" connection of the relay switch. The small hose on top of the relay should only have vacuum to it when the dash switch is pulled out, if not then it is backwards at the dash. Now lets look at the relay itself. It has a piston inside that connects 2 ports at a time to vacuum. With that in mind the piston should be in the full down position when the car is running or not connecting the yellow and green hoses together and the red is vented to atmosphere keeping the doors closed. When vacuum is applied from the dash switch to the relay via the small hose on top the piston moves up connecting the red and yellow hoses together and the green is then vented to atmosphere causing the doors to open. The small hose on the relay does the same job as flipping the manual switch on top of the relay only it does it internally.
This is how the doors work. You cannot move the actuators with vacuum applied to both sides. To verify what I am saying go buy, borrow, or rent a hand operated vacuum pump and hook it up to the actuators and see how they work. This can be done on the car without starting it. then hook it up to where the yellow hose connects to the relay and use the manual switch to open and close the doors. It does take a while and you hand will hurt but you will see the whole process fall into place and start to make sense.
I wish that AL would put this info in the tech section of the site as to benefit everyone.
