I have a 2002 Deville with an interesting lock situation. Im not sure what topic to put this question under but i figure that general techs may have some good ideas for me to try.
The back right door panel was taken off this morning to put a new roter on for the window. The windows all work now however the door locks are now not working correctly (they worked fine before- not sure if its coiincidence now or not).

When off, the driver door lock button works fine. But the back doors lock buttons will not work. When running, the driver door will unlock but not lock the doors, theres not even a sound when the button is hit to lock. And the back still doesnt work.

Anyone have any idea what may be causing this or how to fix it?
