Thought I fixed my rear hatch lock but now...

it doesn't work. I did a ton of research on the site and read much of the posts regarding vacuum leaks, etc.
First, I adjusted the actuator away from the mechanism to take up any slack. I also spray-lubed all the linkages to loosen 'em up.
Then I plugged all lines leading to and from the gas cap actuator, a trouble spot as I learned from researching the forum.
I tested it several times and seemed to work alright so I put everything back together, feeling rather satisfied.
Now this AM there is nothing, not even the doors are working!
Huh?

Oh, an interesting point: just for fun I swtitched the lines leading to the lock actuator and it worked well, albeit the opposite of everything. What would that mean?
Thanks in advance for responding with any guidance you might have.
